Front End

Front “lips” are used to give your car a different look from the crowd if you want to retain the stock bumper and can even provide aerodynamic benefits. Other wise there are many aftermarket companies that manufacture bumpers that will give your car a completely new look.

Splitters are a complimentary addition to front lips with the sole purpose of adding downforce for track purposes. The angle of the splitter in the example below is adjustable by the rods on either side of the intercooler.

 

Canards are fin-like additions that are fitted to the corner of the front and/or rear bumpers. This adds even more downforce for track performance.

 

Side Skirts

Side skirts add extra aesthetic appeal, completing the look of the front and rear lips. Also side splitters can be added to the underside of side skirts to direct passing air. This will streamline the passing air and reduce vortexes.

Rear End

Similar to front-end modifications, rear ends can be fitted with either an entirely new rear bumper or a rear lip added to the factory bumper. Rear ends can also have a “diffuser” fitted under the car near the rear axles and sits either flush or a few inches past the rear bumper depending on the design. Again, this streamlines the air flowing under the car to reduce vortexes.

Spoilers, also known as wings, can be fitted for aesthetic appeal and/or track performance. They come in various shapes and sizes but their main purpose is to add downforce to the rear end of the car. This helps keep the car planted to the ground, especially at high speeds.
