The Subaru BRZ is an excellent handling vehicle with good aerodynamics. Take it a step further with the AVO Fiberglass Front Underspoiler, designed at tested for the track. It keeps air from going underneath the car, pushing it up and through the bumper and over the front of the car. This improves stability and handling immensely, especially in high speed corners. An added benefit is that more air goes through the bumper and thus through the radiator, improving cooling performance at high speeds.
