APR FRP Rear Diffuser Subaru WRX STI 02-07
Diffusers work in conjunction with other aerodynamic components of a car to help produce downforce. Because a car displaces air as it moves forward, the air molecules in the rear of the car get disrupted causing a vacuum of low pressure air.
To help channel the high speed air flow coming from underneath the car, diffusers redirects the high speed air flow to transition smoothly transition into the low pressure vacuum in the rear. This encourages a smoother flowing air flow underneath the car and allows better performance from other aerodynamic components such as aerodynamic wings.
- Works with other aerodynamic components to:
a) Reduce drag.
b) Reduce lift.
- Adds aggressive appearance.
Constructed from Fiber Reinforced Plastic (FRP)
Since 2002, APR Performance has created special project vehicles that highlight our company’s capabilities at producing quality products. Every APR Project vehicles are debuted at the Specialty Equipment Market Association (SEMA) Show in Las Vegas, Nevada. APR manufactures high quality aerodynamic components from carbon fiber and fiberglass. They are well known with their adjustable carbon fiber GTC wings and front wind splitters. APR has also created many widebody kits as seen on the STI, EVO VIII, Celica, and S2000. The APR product extends to aero mirrors, strut bars, radiator shrouds, rear diffusers and more. APR products are designed for performance and proven on the race track.
