Purchase STI Side Under Spoilers from Carlsen Subaru, serving San Francisco

Improve the form and function of your Subaru WRX with these STI Side Under Spoilers. These side panels for your Subaru WRX or WRX STI will add both visual flair and a tangible performance increase - a rare combination. Whether you're getting ready for track day or just the morning commute, these STI Side Under Spoilers will improve airflow and give your vehicle an aggressive edge that'll stand out at a stoplight.

Performance Advantage of STI Side Under Spoilers

By smoothing airflow under your car, and limiting turbulent air slipping beneath your car from the sides, these under spoilers reduce drag and limit the effects of air resistance working against the engine. They also visually lower your vehicle, extending your rocker panels further down the sides for an aggressive, race-ready look. For optimal downforce improvement, combine these Side Under Spoilers with Front and Rear Quarter Under Spoilers for the slipperiest airflow beneath your WRX.
