APR Rear Diffuser
2002-2007 Subaru Impreza WRX/STI
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.
