Diffusers & Vortex Generators

Vortex generators benefit cars that have rear wings because it keeps the air flow hitting the top of the rear spoiler for optimal downforce.

    APR-FAB-820519

    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...

    CUSC-672 487 S

    The STI Rear Diffuser came standard on the 06-07 USDM STi. It channels the air underneath the car to help with high speed stability. You can either purchase the diffuser alone if your car already came with one from the factory or you can purchase the additional hardware in order to bolt it onto your vehicle. This is the bracket that allows for...

    So you’re driving on the road and all of a sudden you see these Subaru’s, and Evo’s with those fin mcthingees on the back of the roof right? What is that? This is called a vortex generator. Simply because they generate a vortex of air particularly for aerodynamic reasons. Vortex generators benefit cars that have rear wings because it keeps the air flow...
