APR Performance Carbon Fiber Side Rocker Extensions (FS-603517) 3511 Hundreds of hours of prototypingAPR Side Rocker Extensions are the next step to help aerodynamically tune the handling of a car. Made of lightweight and durable carbon fiber composites, APR Side Rocker Extensions help reduce lift at high speeds by preventing air at the sides of the car from rolling underneath the car. The reduced lift helps to stabilize the car during high speed cornering and helps to increase traction for faster lap times. Features: Carbon Fiber Construction All
