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.
