There are many different aerodynamic concerns to take into account when a vehicle is being designed. One of the fundamental problems with the shape of any automobile is that they are essentially shaped like a wing, which means that the faster a car travels, the lighter it becomes. A light car does not produce the same kind of force that the tires need to grip, so while lighter equals faster, it also reduced handling. There are a number of different aerodynamic elements that are added to racing cars and nowadays to street cars to reduce this effect. One way to reduce aerodynamic turbulence is with the addition of APC side skirts. APC side skirts fit along the sides of the car in between the wheels. They are designed to reduce lift generating air flow, drag, and to prevent cross winds from upsetting the vehicle. APC side skirts also look phenomenal when combined with other elements of an APC body kit, such as an air dam or a rear valence. With APC side skirts, you can also enhance the "slammed" effect that you might be going for. APC side skirts are fairly simple to install, although for some models, some drilling may be required.
