The APR APR Side Skirt Diffuser for the 15+ WRX and WRX STI add great performance and looks to your Subie. The Rocker Extensions are made of lightweight and durable carbon fiber composites that help reduce lift by preventing air from the sides of the car from rolling underneath. 

The reduced lift helps to stabilize the car during high-speed cornering and helps to increase traction for faster lap times. This is a must for the track-minded build!
