02-07 WRX / STI APR Performance Carbon Fiber Rear Diffuser

This is the APR Carbon Fiber Rear Diffuser designed to give your vehicle aggressive race-inspired looks but to more importantly, improve the overall aerodynamics of your vehicle. This is especially beneficial for those of you who participate in high-performance driving events such as a weekend time trial or in any other motorsport event that will have you going through high-speeds. The rear diffuser will generate a venturi effect which will create a higher vacuum between the bottom of your car, and the surface of the road when air passes through at a high rate of speed which will pull air from the rear section of the vehicle and allow the air to expand, causing more downforce.

APR uses high-quality carbon fiber materials that are lightweight, yet durable to handle the conditions. This rear diffuser will come in a glossy carbon fiber finish and will go along well with a stock-bodied vehicle, or it will also go excellent with the rest of your carbon fiber bits.

This is a two-piece design that will come ready for the installation.
