Basic knowledge reserve of car air kit modification for aerodynamic applications
Adding a rear wing, adding a front lip or changing a surround is a very common thing for modding players. I don’t discuss how much downforce it can increase, how to spoil it, just add/modify aerodynamic kits After the appearance of the vehicle is improved, the money is worth it. However, when we go to the auto parts city or the modification shop to buy aerodynamic kits, the problem arises: the same part often has completely different names in different shops, which makes many modification players feel very at a loss.
Car front bumper. The common modification method is to purchase the products of modification manufacturers for replacement, and a considerable number of car owners who want to retain the characteristics of the car series will replace the surrounds of higher-end models, such as the Golf 6 to replace the GTI or R20 front bumper, and the BMW 1 series to replace the M series front bumper. bar etc.
When it comes to the front surround, we have to talk about the front bumper, whose scientific name is the front spoiler. The front bumper is one of the aerodynamic components we are very familiar with. It originated in the racing field and can increase the downforce of the front of the car. However, its effect is not obvious when used in civilian modified vehicles, and it is more inclined to improve the visual effect of the vehicle. Moreover, the price of modifying the front lip is cheaper than the overall replacement of the large surround, and it is more and more popular with civilian modified cars, especially some owners of appearance or light modification.
Next, let's take a look at another aerodynamic component on the front bumper - the front bumper deflector, commonly known as the air knife. Air knives are the most widely used in racing cars, but with the development of the modification industry, this aerodynamic component is also appearing more and more in civilian vehicles. Of course, it is impossible for a civilian car to gallop at a high speed like a WTAC racing car, and the downforce provided by the air knife at low speed is basically negligible, but it can still bring quite good visual effects in appearance.
After reading the aerodynamic parts of the front, let's take a look at the aerodynamic parts on the side of the body.
Side skirts refer to the skirts installed on both sides of the car body (the bottom of the door and the link area of the chassis), which are used to reduce the airflow entering the bottom of the car from both sides of the car body, and have a certain spoiler effect. It can reduce the generation of reverse airflow and improve the high-speed stability of the vehicle. On cars with wide-body kits, the side skirts are also an important bridge connecting the overall lines of the body. They are used together with the front and rear spoiler kits to make the air flow more smoothly. In addition, the side skirts are also the basic components of the appearance upgrade, which can play a certain decorative role.
The next thing to talk about is the bullet-type rearview mirror. Bullet mirrors are not as common as front bumpers and rear wings, and are only used in a small number of modified cars, racing cars and supercars. Although the use of bullet-type rear-view mirrors can reduce air resistance, and the brackets of the rear-view mirrors also have a spoiler effect, the field of view of the rear-view mirrors will be greatly reduced, which is not conducive to daily forms; and most bullet-type rearview mirrors The mirrors all use carbon fiber shells, which are expensive. Under various conditions, bullet-type rearview mirrors have not been popularized, and very few are seen on the road.
The most conspicuous of the aerodynamic kit at the rear of the vehicle is the rear surround, rear wing and diffuser. Look at the rear surround first. Rear surround, also known as rear bumper. Usually, the rear surround, front surround and side skirts are combined into a set of large surrounds for sale, so that the front and rear styles of the air kit are consistent and achieve a better appearance. Of course, some players have used the same method as replacing the front surround to directly transplant the rear surround of the high-end car.
After talking about the surrounds, it is natural to talk about the diffuser. Diffuser, commonly known as tail lip, rear lip and rear spatula. The diffuser quickly discharges the airflow under the vehicle through the upward-turned deflector, which increases the pressure difference between the roof and the bottom of the vehicle, making the downforce more invisible. The diffuser can only function properly on a flat road. Generally, the municipal roads on which civilian vehicles drive are not flat, and even if a diffuser is installed, it is difficult to play an effect.
The last thing I want to talk about is one of our common aerodynamic kits - the rear wing, also known as the rear spoiler of the car, the fixed wind wing, which can provide more downforce for the vehicle at high speed. For civilian vehicles, the decorative role of the rear wing is far greater than the actual role. First of all, when the vehicle speed is lower than 100km/h, the smaller the protrusions on the body surface and the smoother the lines, the smaller the wind resistance will be. At this time, the rear wing will increase the air resistance. The advantage of the rear wing can only be achieved when the vehicle speed exceeds 120km/h. be highlighted. In addition, in order to obtain good downforce, the material, angle and even adjustment range of the rear wing have to undergo a series of tests and adjustments, which is not a simple matter.
