TRUNK SPOILER IMPREZA 4Door(GV)

This Trunk Spoiler is the same shape as the part used on the STI complete car "WRX STI tS". It is an aerodynamic part that improves rear tire traction by using the flow of air across the body while driving to apply down force. Geometry that has been shown to achieve the best performance during repeated wind tunnel testing of actual cars provides an optimal balance of air resistance (Cd), front-to-rear aerodynamic lift (Clf/Clr), and down force to improve stable control while driving at high speeds.
