Why choose carbon fiber tuning parts ?

Working principle:

According to the principle of aerodynamics, the automobile will encounter air resistance when driving at high speed. The aerodynamic force of the three directions of longitudinal, lateral and vertical rise will be generated around the center of gravity of the vehicle, which is longitudinal air resistance.


In order to effectively reduce and overcome the influence of air resistance in high-speed driving of automobiles, people have designed and used automobile tail wings, whose function is to make the air produce the fourth force on automobiles, that is, to produce greater adhesion to the ground, which can offset part of lift, effectively control the floatation of automobiles, so that the wind resistance coefficient is reduced accordingly, so that automobiles can run close to the road and ground, thus. Improve the driving stability.

Subtitle Description



The function of automobile tail is to make the air resistance form a downward pressure when the automobile is running at high speed, to offset the lift as far as possible, to effectively control the downward pressure of the airflow, to reduce the wind resistance coefficient accordingly, and to increase the high-speed driving stability of the automobile; because the tail can reduce the air resistance of the automobile, it is also helpful for the high-speed automobile to install the tail to save fuel. Make the shape of the car more beautiful, play a certain role in decoration.


Carbon fiber tuning parts body kits - What Are They and How Do They Work? | All-Fit Automotive

There are many aftermarket accessories that can improve the performance of your car.

Some accessories are parts or components you attach to the engine or exhaust system.

Others, such as car splitters, are parts you build into the frame of the vehicle.

Engine modifications, such as turbo chargers, are straightforward, but what about car splitters? What exactly are they and how do they work?


What Is A Car Splitter?

A car splitter is a modification to the body of the car that is usually attached to the bottom of the front bumper. Splitters look like a flat scoop that extends out from the bottom of the front of the car.


Splitters are often made from carbon fiber or other similar durable materials. Splitters sometimes have support rods that are attached between the splitter and the bumper, which keep the splitter parallel to the ground.



How Do Car Splitters Work?

So how does a car splitter – simply a rigid extension of the lower bumper – contribute to the car’s performance? Well, when a car reaches high speeds, air pressure builds up at the front of the car. A lot of this high pressure, low-speed air ends up underneath the car. With only (page 3)low pressure air above the car exerting itself on top, the car experiences lift, with the front of the car lightening up. This results in reduced traction on the road.


A car splitter forces the high pressure air upwards, where it builds up around the bumper and migrates up and over the car. The high speed, low pressure air passes underneath the car. Combined, this reduces vehicle lift and results in a net positive downforce. This gives the car more traction as it hugs the ground. Many drivers combine a splitter with a front air dam or front bumper (PAKGE 4)openings that direct the extra air into the brake ducts or radiator for cooling. Car body upgrades in general are all for redirecting air to carry out various functions.
