Why do you need a spoiler on a car? Its advantages and disadvantages
Car tuning is in vogue these days. In addition to various body kits and other fashionable elements, car spoilers are popular. Some drivers perceive them as design elements, while others are confident that this body element provides some advantages. Let's try to figure this out.
Why a spoiler on a car?
Let's start with something simple. This element sets the style for the entire car and makes it sporty and unique. It is primarily used for car styling. Secondly, it is used as a practical element that improves the aerodynamics of the car by redirecting air flow.
In simple terms, a spoiler at high speed allows you to press the rear of the car to the road, which will contribute to better grip of the wheels on the asphalt. On cars without a spoiler, at high speed the rear rises under the influence of air flow under the car body.
For this reason, the grip deteriorates.
How does a spoiler work on a car?
At high speeds, the oncoming air flow becomes strong. It gets under the bottom of the car and lifts the body above the road. Vortex air currents form behind the car, which slow it down a little. All this increases the aerodynamic load on the car. The spoiler allows you to direct the flow in the right direction, which will eliminate unnecessary loads.
It is recommended to install two spoilers: front and rear. The rear one presses the rear of the car to the track at high speeds, which allows you to slightly unload the front axle. The element at the front presses the front axle. It may also have built-in deflectors that direct air flow to the brake pads or discs, which helps to cool them better.
Classification
Depending on what exactly the owner wants to achieve by introducing this structural element into the design, spoilers can be divided.
By design they are:
- Custom. Manufactured according to individual customer design. This is an expensive, unique item that is not found anywhere else.
- Factory ones. They are produced at the factory, produced in large quantities and have the appearance of a factory structural element.
By mounting method:
- Supporting. They are fastened using special supports, which are often simple self-tapping screws or bolts. Despite the roughness, this is a fairly reliable fastener.
- Sticky. You can guess the mounting method already from the name. Such spoilers are attached using double-sided tape or glue. The reliability of such fastening does not inspire confidence. There were cases when such elements simply flew off cars at high speed.
At installation location:
- Rear. They are usually installed on trunks or below the rear window.
- For the roof. Most often installed on hatchbacks, rear doors.
- Skirts for rear and front bumpers.
- Diffusers. They are impossible to notice because they are installed under the underbody.
- Side spoilers, which are linings on the threshold of a car.
By application:
- Universal - can be installed on many machines.
- Special - installed only on a specific model at the factory.
Advantages
A car spoiler can have both advantages and disadvantages. Let's start with the fact that this is not just an expensive toy, but an expensive structural element that can even harm the car.
If it is installed by a person who does not understand the topic, he will most likely do the installation incorrectly. And then such an element on the car will be useless, and at high speed even dangerous.
Then why do you need a spoiler on a car? Its main purpose is to enhance tire grip and improve handling. This can only be achieved if installed correctly.
So, the main advantage of installing this structural element is improving the car’s handling by increasing the coefficient of adhesion of the rear wheels to the road. The car will not drift to the sides.
The second advantage is reduced fuel consumption. Air flows at high speed create resistance to the movement of the car, which causes the feeling that it is slowing down. At the same time, the driver tries to maintain speed and presses the gas pedal, which leads to excessive fuel consumption. The spoiler reduces air resistance, which results in lower gas mileage.
Additional safety is another reason why you need a spoiler on your car.
Due to the fact that this part redirects air flows when moving, the likelihood of the vehicle skidding is reduced, and it becomes more maneuverable. The risk of getting into an accident is reduced.
It also makes braking more effective, especially in winter. And if additional threshold extenders are installed on the sides, the braking efficiency will be even higher.
Flaws
Disadvantages only occur if this element is installed incorrectly.
An incorrect position relative to oncoming air flows will significantly worsen aerodynamics, air resistance will increase, and this will lead to additional fuel consumption.
Also, in case of loss of controllability, it is much more difficult to straighten the car, and at high speeds, the clearance between the road and the bottom will greatly decrease. This is dangerous on bad roads. All these shortcomings are clearly visible in plastic car spoilers.
Conclusion
A properly installed spoiler is really useful and effective, so the desire of many owners to install it is logical. Some drivers want to know how to make a spoiler for a car themselves, but this is a bad task.
To make a spoiler yourself, you need to make an aerodynamic calculation of the car and only then determine the shape of the future element and its installation location.
Otherwise, it will be harmful, so you won’t be able to make and install it yourself.

Why do you need a spoiler or wing?
Surely every car owner who is involved in tuning has at least once thought about installing an aerodynamic body kit on his car, or at least its main components.
Such a body kit works not only to give the car an aggressive or sporty look, but also to improve its behavior on the highway (usually at high speed), in other words, to increase driving performance.
Each component of the body kit has its own explicit function, for example, the body kit of a car works to remove side turbulence that pushes the car off the road, and the bumper body kit is able to prevent, again, all sorts of air turbulence that occurs behind the car, etc. One of the important elements of the body kit is the spoiler and wing. Because the spoiler and wing are considered the main parts of the aerodynamic body kit. Let's look at them in more detail.
How does a wing work and why is it needed?
The wing is essentially the same wing that airplanes have, only inverted. However, this wing does not lift the car into the air, but on the contrary, it presses down and presses down more strongly, the higher the speed, as well as the area of the entire wing.
Compared with other components that are of great importance for the aerodynamics of a car, the impact of the “correct” wing is about 50%.
The “correct” wing cannot be too tiny and should not be located very close to the car body, because at best it will work like a regular spoiler, but at worst, as they say, it will turn out to be non-functional.
Now about the shortcomings. When moving at high speed, the increasing load on the wheels increases the mechanical costs of their rolling. In addition to all this, the wing provides auxiliary aerodynamic resistance, which only increases with increasing speed. The wrong shape and installation of the wing will simply slow down your car, which can lead to excessive fuel consumption.
Why do you need a spoiler?
Spoiler - increases the downforce of the car on the rear and front axles, entails the least amount of energy costs when air flows around the car body. All of the above advantages of a spoiler allow you to improve the car's controllability at high speeds, which increases traffic safety.
Structurally, there are many types of spoilers - a small rear window visor, an independent component on the trunk or the back side of the roof. For cars, a correctly installed and very important designed spoiler is quite capable of replacing a wing. In addition to all this, a spoiler (especially the front one) will help save gas when traveling at high speed.
At the moment, the popularity of spoilers is very noticeable; they can even be found on trucks.

Spoiler and wing

Every driver who improves his car has more than once thought about changing the aerodynamics of his car through an additional body kit.
Such improvements are made not only to give a sporty or aggressive look, but also to improve its driving characteristics, most of which concerns the vehicle's handling at high speeds.
Each part of such a body kit performs its own functional feature. For example, changing the car's sills is done in order to divert side turbulence to the side, which prevents the car from being excessively pressed into the road.
Changing the bumper directs the air flow behind the car in the right direction, and other changes improve the aerodynamics of the car. The most important components of a body kit of this type are the wing and spoiler.
Since these are the components that are rightfully considered the most important and determining the body kit, therefore they need to be discussed in more detail.
You won’t be able to do chip tuning yourself without certain skills. And you can do external tuning yourself. To do this, you just need to first select which tuning elements to apply.
You can consult specialized websites on the choice of body kits, spoilers, wings, moldings, etc. I draw your attention to an online store specializing in the sale of tuning products and installation services.
Aerodynamic body kits for tuning the land cruiser 200 2016 cost from 30,000 rubles, depending on the configuration.
What is the principle of operation of the rear wing and its necessity?
At its core, a wing is an analogy of a simple wing, with the only difference being that it is inverted. And its action is opposite to the wing of the aircraft.
The wing is not designed to lift the car, but, on the contrary, to press it against the road surface, and the downforce directly depends on the area of this body kit and the speed of the car.
When comparing the importance of other components for improving aerodynamics, the impact of the anti-wing with proper installation takes up the entire 50%.
And therefore, a correctly installed wing simply by definition cannot be large in size, however, like its installation in close proximity to the car body, which does not also give good results. In the best case scenario, it will work on the principle of a spoiler, but when considering the worst case scenario, the functionality of this part of the body kit will be completely absent.
While there are undoubted advantages, one cannot remain silent about the disadvantages inherent in the wing. At high speeds, the load on the wheels inevitably increases, which generates force expended on their torsion.
Plus, the increasing speed of the vehicle increases the aerodynamic resistance.
Therefore, incorrect installation of such a wing will slow down your car, which will lead to excessive fuel consumption.
What's so great about a spoiler?
The presence of such a part of the body kit as a spoiler increases the downforce acting on the rear and front axles of the car, which makes energy costs when the car interacts with the air minimal. Such indicators invariably affect the controllability of a car traveling at high speed, making travel in such a car safer.
There are many types of spoilers:
- - in the manner of a small visor flaunting over the glass installed at the back;
- – as a separate component mounted on the trunk lid, or on the roof in the rear part.
A car equipped with a properly installed and, most importantly, well-designed spoiler can easily do without a wing.
In addition, spoilers (mostly front ones) significantly affect fuel economy when driving at high speeds.
Today, the demand for spoilers is constantly growing and even trucks are equipped with them.

Decorating a car with a spoiler?
Some - right away, some - over time, they want to somehow refresh the appearance of their car, add some kind of zest so that it becomes different from everyone else.
Such an activity can be very addictive and turn into a hobby; in short, some are predisposed to such a disease as tuning. Are there any of you reading this? Most often, the first symptoms are thoughts that exhaust the brain: “If only there was a spoiler for my car...”.
And then look at examples of cars with tuners on the Internet. It’s like wanting a tattoo, getting one and off we go...
An addition such as a spoiler, if chosen wisely and tastefully, can really make the car more expressive. And if you are just thinking about aerodynamic tuning, we will give you some advice, or rather, we will analyze what the pros and cons of spoilers are. Perhaps this will help you decide.
Why a spoiler?
A “spoiler” is an element or a symbiosis of elements capable of changing the aerodynamic properties of a car body by redirecting air flows - it tells us about the first purpose of such a car gadget.
Namely, to put it in simpler terms, a spoiler helps provide the car with a greater degree of stability on the road at high speeds, better handling, stability in corners, and reduce the risk of skidding. Experts have found that the effects of aerodynamic forces on a car begin at speeds of 80-90 km/h.
And the correct, well-chosen and installed spoiler begins to manifest itself precisely in this range. The thing is that the oncoming air flow (starting from a speed of 80 km/h and the higher) goes around the car body not only from above and on the sides, but also from below. And due to this flow under the bottom, the car rises above the road, that is, the adhesion of the tires to the asphalt worsens.
And also after the air flow goes around the car, it will again strive to fill the space that was occupied by the car. Some vortex flows will begin to form behind the car, and this will slow down the car. This is where spoilers come in.
The second purpose is the aesthetic component. To make it beautiful, more sporty! It’s not difficult to guess that such decoration on civilian cars migrated from motorsport.
And to a greater extent it only makes it more menacing, since cars designed for any serious speed have been tested for aerodynamic resistance by the element and do not need additional “wings”.
In sports, the aerodynamics of a car are on the same level as the characteristics of the engine! But, in any case, the correct installation of a spoiler can improve the aerodynamics of your bucket by 1.5% and increase downforce on the rear axle by 15%.
And thirdly, in some cases, the spoiler reduces the ingress of dirt, dust, and water onto the car windows due to changes in the characteristics of the air flow. Basically, all these three answers to the question “Why?” and there are advantages to spoilers.
Spoiler classification
At installation location:
- front ones - reduce the air flow passing under the car. Installed at the bottom of the front bumper, adjacent to it with the rear edge. The air above the splitter is vented to the side, along the wheel arches, or through the car body, through the ventilation holes in the bumper. The front spoiler can also perform additional cooling functions for brake discs, pads and
- drums, radiator cooling system, and air conditioning. After all, it has built-in deflectors in the form of channels through which oncoming air is directed in the desired direction.
- rear ones (located on the trunk lid) - functionality similar to the front ones. Its use is more appropriate on rear-wheel drive vehicles, which in turn ensures the impact of aerodynamic downforce on the axis and better contact of the wheels with the road;
- roof spoilers;
- skirts for the front and rear bumpers - serve for additional pressing load using air flow and make braking more effective;
- diffusers (can be installed through elements of the car body or under the bottom).
By design:
- custom (Custom Style) - exclusive options, produced in a single copy or in a limited edition;
- factory (OEM Style) – mass produced;
By default:
- station wagons - suitable for any car model;
- special - for one specific model or several.
Fastening:
- sticky (Lip spoilers) – attached to the body using glass glue or double-sided tape;
- on supports (Post spoilers) – mounted on the body using self-tapping screws or bolts.
Minuses
These include (and they appear mainly when installed incorrectly):
- lowered ground clearance;
- increased fuel consumption;
- deterioration of the aerodynamic performance of the car if the spoiler is not selected/installed correctly. This implies deterioration in handling and safety;
- Most of the offered and affordable spoilers are plastic. Their disadvantage is that they wear out quite quickly. And models made of carbon fiber and aluminum are an expensive pleasure.
Bottom line
In short, it's a double-edged sword. Actions according to the principle - bought it, stuck it on, rather for a ride (if it is still important for you that it works at speeds and in sharp turns) - is not a safe activity. The aerodynamic balance of any car was initially calculated by professional designers at the manufacturer.
And they designed the body without taking into account spoilers and other frills. This means that aerodynamic elements must be installed by professionals, and these elements must be selected wisely, and not some kind of universality.
If you are not a fan of fast driving, your element is the city mode and its strict observance - sculpt spoilers for beauty for your health! After all, if you choose it tastefully, it really is a plus for the appearance of your car.

Why do you need a spoiler and wing?
Any motorist who has been involved or interested in car tuning at least once in his life has heard about body kits.
It is worth noting that an aerodynamic body kit on any car is needed not only to give it an aggressive or sporty appearance, but also to make the vehicle more sensitive and efficient on the road (especially at high speeds).
Almost any driver strives to increase driving performance, and especially those who take tuning their car very seriously.
Each of the components of the body kit has its own function, for which this part is used. For example, the body kit of the vehicle sills is installed to remove lateral turbulence. For what? So that they do not push the vehicle away from the edge of the road.
But the bumper body kit is used to prevent any air turbulence from appearing behind the car. And there are quite a lot of such parts; using them all together is the personal desire of a particular driver. Many rightfully consider the spoiler and wing to be one of the most important parts of the body kit.
It is worth considering each of these details separately.
What is the wing used for and what is the mechanism of its operation?
The wing of a car can be compared to the same wing that every airplane has, only it has the opposite position relative to the surface of the earth (inverted). Don't think that with a wing, your car will fly into the sky.
Quite the contrary, it presses the car against the road surface, and the pressure force increases in proportion to the speed of the vehicle and the area of the wing itself.
It is difficult to overestimate the importance of this element, because when using the “correct” wing, the aerodynamics of the car improves by an average of 50%. It is important to understand that this part cannot be small.
In addition, the wing cannot be installed very close to the car body, otherwise it will become a simple spoiler or even lose all its functions and will be useless.
If we consider the disadvantages of the wing, it is worth noting that the car, moving at high speed, experiences a greater load than usual on the wheels. This in turn increases the mechanical stress and costs required for movement.
It is very important to install the wing correctly; incorrect installation can have the opposite effect - it will simply slow down the car due to auxiliary aerodynamic counteraction. As a result, fuel will be consumed in large quantities.
What is a spoiler used for and how does it affect the car in motion?
A spoiler is used to reduce energy costs by allowing air to flow around the vehicle. This is achieved by increasing the downforce of the vehicle on the rear and front axles. As a result, the car becomes more controllable at high speeds, which also guarantees a higher level of safety.
In general, there are quite a large number of varieties of spoilers, including structural ones. So there are small visors for the rear windows, separate spoilers on the trunk or behind the roof.
If you install this part correctly, you can completely do without a wing without feeling much of a difference.
Don't forget the fact that the spoiler also reduces gas costs when driving at high speeds.
Today, spoilers are very popular; they are found not only on passenger cars, but even on trucks.

Why do you need a spoiler on a car?
11:19, May 20, 2015
Why is a spoiler installed on the trunk lid of a car? Of course, in most cases it has an aesthetic function. Some car models look completely different when they have a wing installed on them.
But initially the spoiler had an important function - it pressed the car to the ground while driving at high speeds. Due to the fact that it “presses down” the rear of the car, it stands better on the road and can reach higher speeds.
On some cars, spoilers are installed by the manufacturer, and sometimes the owners themselves add this zest to their iron horse.
Thus, the wing can serve two purposes: it improves car control and is a decorative element.
Spoilers of the first category often look bulky and sloppy compared to the second category. While there are a huge variety of spoilers of the second type, and everyone can choose the appropriate design for their car.
Operating principle
When driving at high speed, the car cuts through the air flow, which reduces the stability of the vehicle by creating vortices behind it. And the spoiler “cuts” these vortices, preventing them from rocking the car.
But in some cases, a spoiler alone is not enough, for example, if the car is capable of reaching high speeds or is rear-wheel drive.
In such a situation, the front part of the car also rises while driving, which leads to a deterioration in the response to turning the steering wheel and an increase in fuel consumption.
Then, in addition to the rear wing, aerodynamic body kits are installed, the effect of which is similar to that of a spoiler. All this together improves the road performance of the car.
Flaws
Since the spoiler presses the car, it is natural that the ground clearance will decrease, which is a noticeable drawback when the roads are in poor condition.
The wing also interferes with visibility through the rear window, although car owners quickly get used to this inconvenience.
The cost of the spoiler itself and its installation is often high, so not all car enthusiasts can afford such a decorative element.
Bottom line
Spoilers can be divided into two categories: some serve technical purposes, while others are a decorative element. So if you decide to equip your car with a spoiler, you need to take into account its considerable cost. In any case, installing a wing cannot harm the car and its behavior on the road.

What is a spoiler for?
Probably everyone has noticed on cars, be they ordinary production cars or sports or racing cars, the presence of an interesting component such as a spoiler. First of all, its main task is to provide the necessary aerodynamics, and lastly, external beauty.
One of the purposes of a spoiler is to reduce the level of wind resistance. It is typically installed on trailer cabs, trucks with trailers, and motorcycles.
With its help, it is possible to achieve better aerodynamics, reduce the load on the body, and reduce fuel consumption. Often a spoiler is installed in order to change the direction of air flow.
It is mainly placed in the rear of the car body, often in hatchbacks, in order to minimize the sticking and splashing of the rear windshield with dirt and dust.
For a spoiler, there may be another direction for its use, for example, acting as a wing.
Let's give an example of a frontal design, when it is placed in the area of the front bumper or in the areas of the sill extensions, the so-called side spoilers.
Their presence at high speeds leads to the formation of rarefied air under the bottom, which is accompanied by an increase in aerodynamic drag and the generation of greater downforce, which helps keep the car on the track.
A spoiler is often the main detail of car tuning, and successful selection of the required option will add individuality and uniqueness to the vehicle.
Today, spoilers are made from various materials, including carbon fiber, carbon fiber, aluminum, and others. In order to attach it to the car body, you will need special fasteners, metal brackets and reliable special glue that secures the threaded connections from spontaneous unscrewing.
When installing a spoiler, everyone must understand that this element of the car will also pose a serious danger both to you and to other road users. This is especially true if the spoiler is not installed properly.
There are a lot of cases of its separation from the body; it is good if at this moment there is no one behind you, since at high speed it is impossible to predict the direction of flight of this part.
Since spoilers are attached with hardware, to install them in the car you will have to locally damage the body by opening the mounting holes.
If you are planning to buy a spoiler on the market, then in this case we are talking about a universal option, and, most likely, you will not be able to achieve anything other than aesthetic beauty from it.
They are often installed on the trunk lid as a tuning element.
To achieve the aerodynamic performance of a spoiler, it must be specially designed for a specific car model, and the work must be done by specialists who understand this specificity.
The spoilers on sale today are made in such a way that they can be installed on almost any car.
But for those cars where the spoiler was provided by the manufacturer, it is not recommended to remove it or replace it with a new one, since such actions can have the opposite effect.
After all, the designer designed it for a specific purpose. In addition, the presence of empty mounting holes in the body is unlikely to decorate your car.
The specificity of the wing spoiler is such that it clearly causes a deterioration in the dynamics of the car, but it is installed in order to increase the downforce of the vehicle.
It is usually subject to quite serious loads, so the strength of its structure is very important.
Fake spoilers will only improve the design of the car, but they can change air flows in unpredictable directions, so you should expect a deterioration in aerodynamic parameters from their installation.
Not a single spoiler will turn a Zaporozhets into a Formula 1 car, but it is quite possible to achieve a sporty, aggressive look, bright and attractive design.

Why do you need a spoiler or wing?
Most fans of both fast driving and those who want to show off the appearance of their car often face the question - is it necessary to install a spoiler or wing ?
Installing these elements usually serves two purposes:
- tuning - beautiful appearance of the car;
- qualitative improvement - stability and aerodynamics of the car;
As for beauty, the installation of these elements will certainly add sportiness and aggression to the appearance of the car, but consultation with a specialist is necessary, since tuning does not always mean beautiful, and this moment must be “approached” responsibly, and incorrect installation can worsen the performance of the car.
Purpose of the wing
The rear wing in a car is similar to an aircraft wing, only installed in reverse, and its forces are distributed accordingly.
It does not work to lift the car, but directs the air flow to press the car to the ground. The force of the air flow on the car depends on the speed of the car and the dimensions of the wing; it takes on half the aerodynamics of the car. But if its dimensions are not large enough or the installation location is remote from the hood, then there will be no effect from its use.
When moving quickly enough, the pressure on the wheels increases sharply, and an unnecessary obstacle to the air path is formed, which increases fuel consumption and slows down the speed of the car.
Useful qualities of a spoiler
It is necessary to understand that only drivers who prefer fast driving need to install a spoiler on their car. Then this part of the body kit can significantly increase driving safety. The spoiler has an effect at speeds of more than one hundred kilometers per hour. In all other cases, it is a beautiful decorative detail.
The main purpose of this link is to redistribute the oncoming air flow. Thanks to the installation of this device, the car's handling improves, gasoline consumption decreases and dirt almost completely disappears from the rear window.
Installing a spoiler leads to a decent increase in pressure, which seals the car to the road, thereby reducing the flow around the body.
The most effective installation of this part is considered to be on trucks. By blocking part of the space above the driver's cabin with a spoiler, fuel consumption can be reduced by 25%.
But the newest and most expensive spoiler, installed at the wrong point, can cause an accident. The lifting force of the car drops significantly, and the redistribution of the load along the axles makes the car difficult to control at low speeds. Also, installing a front spoiler threatens loss of control if the car is slightly tossed over a bump.<\p>

Why do you need a spoiler or wing?
Home » Autolife » Why do you need a spoiler or wing
A spoiler in a car is a device that corrects the aerodynamics of the car body by redirecting air flow and combating pollution. As a result, the aerodynamic drag of the car decreases and downforce increases. Sports and tuning cars are equipped with a spoiler for more efficient movement.
Aerodynamics of a car
When a car reaches a speed of more than 130-140 km/h, a turbulence zone forms behind it, which interferes with the control of the car. While driving, the surface of the car is exposed to air flow from three sides - from above and from two sides.
In the lower zone of the bottom, the flow of air masses collides with parts that protrude, resulting in random turbulence. The area under the car's underbody and engine area is subject to excess pressure. In this case, the machine is raised due to the fact that the clamping force is reduced.
The grip of the tires on the road decreases and driving becomes less comfortable. The aerodynamic body kit consists of the following elements - a spoiler and a wing help solve this problem.
Elements that affect the aerodynamics of a car
There are factors not related to the body kit, but influencing the quality of the aerodynamics of the car. Namely this:
- driving with the windows open;
- side mirrors;
- movement with the hatch ajar and open;
- deflectors;
- additional lighting devices installed on the roof, for example on SUVs.
Spoiler or wing
The most important part of a car body kit and the name of the device for changing the dynamics of aircraft is the spoiler. The difference between automobile and aircraft designs is only in the opposite principle of operation.
For safer driving, speed lovers install a spoiler. Otherwise, the body kit element will serve only for decorative purposes. The body kit will be useful at travel speeds of more than 90 km/h.
Purpose of the spoiler
The main function of this part of the body kit is to redirect the air flow when traveling at high speeds. Handling becomes better and fuel consumption decreases. A spoiler on a car reduces contamination of the rear window.
Where are the aerodynamic body parts installed on the car?
- In the area of the front of the car to the bumper to increase the pressing force while driving. If the car has front-wheel drive, a spoiler will significantly improve handling.
- The threshold area works effectively to resist air masses and their rarefaction under the bottom of the car. The car will become more controllable and more firmly pressed to the road when driving.
- The area that flows from the roof to the fifth door, for example, a hatchback or station wagon body type. This will minimize dirt on the rear window.
- The most common place is the trunk, which will improve the quality of handling (this is especially noticeable on rear-wheel drive cars).
Wing
In its appearance and shape, the wing resembles an airplane wing in an inverted position. This element serves to press the car to the road when driving. Accordingly, the higher the speed, the more pronounced the effect.
Proper installation of the aerodynamic body kit element will have a positive effect on driving performance and will ensure good control. An important point is the correct selection of size and installation location. A very close location to the car body, a small or too large size will not bring the desired effect and will serve as a decorative element.
Cons of wings
- When driving at higher speeds, the load on the tires will double. Mechanical friction will also increase.
- An incorrectly selected wing size will create aerodynamic drag.
- An incorrectly selected shape of the aerodynamic body kit element will only slow down the car. Accordingly, fuel consumption will increase.

Why do you need a spoiler or wing?
Surely many car owners who have had their car tuned have at least once thought about an aerodynamic body kit. After all, such a part can be used both as a whole and in the form of its main components. A body kit is needed not only to give a sporty look, it is needed for improved performance on the highway.
At high speed, these parts significantly improve the car's handling.
All components of the body kit have their purpose. Thus, when using a body kit on the sills, the side wind is diverted, which helps push the car off the road; and the body kit that is used on the bumper can prevent any possible air turbulence.
An irreplaceable element of the body kit is a spoiler, in combination with a rear wing. Let's take a closer look at them.
The wing, in its design characteristics, is a wing characteristic of aircraft, and the difference is that it is simply inverted. Unlike a regular wing, thanks to which you can take off, a wing presses you to the ground. In addition, the higher the speed and area of the wing, the stronger the crushing occurs.
When compared with other components that have a huge impact on the aerodynamics of a car, the effect of a properly positioned wing is estimated to be about 50%.
Such a wing will not be very small and will be located further away from the body.
If the requirement is not met, then it will perform a function characteristic of a spoiler, and at worst, it will generally show its ineffectiveness.
It's time to talk about the shortcomings. At high speeds, the load on the wheels increases. At the same time, the friction force during free rolling also increases.
At this very moment the wing begins to slow down the car, and the higher the speed, the higher this figure.
If the wrong shape or incorrect installation was made, then such a wing begins to slow down the car, and this inevitably leads to an increase in fuel consumption.
What can a spoiler do?
The spoiler increases the downforce of the car on its rear and front axles. This action leads to a reduction in energy consumption, which occurs during the interaction of the car and oncoming air. Thanks to this, the car's controllability increases when driving at high speeds and increases safety.
Spoilers can be used in the form of a visor on the rear window and at the same time have a small size.
It can also be used as a component on the trunk of a car, or installed on the rear side of the roof. If you install the spoiler correctly, then it can completely replace the wing.
Moreover, the front spoiler will help significantly save fuel consumption when driving at high speeds.
Nowadays spoilers can be seen on almost every third car and they are even installed on large trucks.

Main types and functions of car spoilers
Each new generation of cars improves in technical equipment. This cannot but affect the appearance of the car. That is why modern cars are hung with various body kits and additional elements that were practically not installed on cars of the second half of the last century.
The spoiler is not just a decorative item
Most car enthusiasts consider this trend simply a fashion, and few people know the true reasons for installing body kits. Why does a car need a spoiler, especially if it is a slightly outdated model? Is this part of the body really important during operation?

Let's start with the main thing: the purpose of the spoiler and its main functions
Spoilers are used on cars to perform two main functions.
The first is the creation of powerful downforce at high speed, which will not allow the car to lose reliable grip of the wheels on the road. And the second function is purely decorative.
Let's consider the first option for using spoilers. It is no secret that at high speeds (more than 80-100 km/h), the oncoming flow of air flowing towards the car bends around the body not only from above and on the sides, but also from below.
When a certain speed limit is reached, a situation may arise when the car, due to the flow of air under the bottom, can rise above the road surface, which reduces the adhesion of the wheels to the road.
In addition, after the air flow goes around the car, it again tends to fill the space that was just occupied by the car. This causes various vortex flows to appear behind the car. And, as a rule, the air density in such an area is less than the density in front of the car.
This causes the car to brake, that is, it increases the aerodynamic loads that arise ahead. In this regard, spoilers are installed on the car body, which allow you to direct the air flow in such a way as to avoid the negative phenomena listed above.
For these purposes, it is necessary to use not one, but at least two spoilers. Since installing this element at the rear of the car will improve the downforce on the rear wheels, but at the same time slightly relieve the load on the front axle, the wheels of which, as is known, are steerable.
At the same time, installing a front body kit, on the contrary, will create downforce at the front of the car, while the rear wheels may lose reliable grip on the road surface. In the case of rear-wheel drive cars, this will lead to reduced power and increased fuel consumption.
And in the case of front-wheel drive vehicles, the driver loses control of the car when maneuvering on the road. That’s why professionals recommend installing two body kits – front and rear.
By the way, the front spoiler can perform additional functions in the form of additional cooling of brake discs, pads and drums, radiator cooling system, and air conditioning. To do this, the spoiler has built-in deflectors in the form of channels through which oncoming air is directed in the desired direction.
Spoilers are most effective at high speeds
As for the second function - decorative, all the advantages of using spoilers in this segment can be seen at various auto exhibitions and fashionable auto magazines. In this case, one goal is pursued - to make the car unique, individual, and inimitable.
For these purposes, there are entire tuning studios that produce both sets of spoilers and produce them individually according to individual orders. This spoiler function is especially popular in the segment of expensive executive, luxury, and sport class cars.
However, there is also a negative part of such car tuning. First of all, installing spoilers, regardless of what purpose, leads to a significant reduction in ground clearance.
Which, in the conditions of domestic “off-road” conditions, can lead to unpleasant consequences. In addition, the tuning procedure associated with the installation of additional body kits is expensive.
It should be taken into account that the cost of the body kits themselves is not small.
So think about whether it’s worth installing these expensive elements on a car, if after driving along domestic “directions” they can simply collapse.
Materials from which spoilers are made
Previously, all body kits were made of plastic and aluminum. They differed not only in shape, but also in quality.
There were cheap options made from ordinary plastic, which could even be destroyed by vibration.
However, with the development of industry, spoilers made of soft and elastic plastic, or aluminum, began to appear, which perfectly resist vibrations and small impacts.
In recent years, more and more body kits made from modern materials such as fiberglass or similar ones based on carbon compounds have begun to appear on the domestic market. Such new items have a relatively low cost, but in terms of quality and weight they are an order of magnitude higher than ordinary plastic ones.
Spoilers can be installed even on jeeps
Spoiler classification
Absolutely all spoilers are divided (classified) into several types and types.
Firstly, spoilers are divided by type of design:
- custom (have a unique shape and exist, as a rule, in a single copy or in a limited edition);
- factory (spoilers produced on an industrial scale, the appearance of which looks like a factory part).
Secondly, spoilers are divided according to the method of attachment:
- sticky – attached to the body using double-sided tape;
- on supports - mounted on the body using self-tapping screws or bolts.
Thirdly, spoilers are divided according to their installation location on the car:
- rear spoilers (installed on the trunk lid);
- car roof spoilers;
- skirts for front and rear bumpers;
- diffusers (can be installed through elements of the car body or under the bottom).
Well, according to application, there are universal and special types of spoilers. The former can be used for a large number of car models. While the second type of spoilers is intended for installation only for a specific model.
A spoiler can make a car look “aggressive”
What's the result?
To summarize all of the above, we can say that the use of spoilers on cars has both significant advantages and disadvantages. Therefore, in order for the spoiler to bring more joy than sorrow, you should carefully select and install this tuning accessory on your car.
And first of all, you need to answer the question for yourself: what is a spoiler for, what characteristics should it have?
Don't overdo it in your desire to stand out
Depending on the answer, you should choose the accessory that suits you, without forgetting the financial component. And God forbid you turn your car with the help of a large number of spoilers installed into a kind of fake likeness of a vehicle. This will not only complicate its operation, but will also cause obvious ridicule among others.
