An STI spoiler is a precision aero device made for Subaru Tecnica International (STI) cars to help vehicle stay stable and be more manageable. Made of light stuff like carbon fiber or aluminum, it raises downforce at very high speeds, thus the grip and the handling are better. The STI spoiler is a drag reducer also, thus the air flow is smoother and the vehicle is more balanced. Besides performance, it gives a sporty, aggressive look which is in line with Subaru’s racing heritage. By combining style with functionality, the STI spoiler not only makes the STI model visually more attractive but also its driving dynamics are improved to be at the level of super road and track performance.
