Although these components are great at reducing lift, they may not bring the added stability and traction road racers are looking for when taking fast turns. APR Performance utilizes these components and integrates them with a Front Air Dam. The APR Front Air Dam goes beyond reducing lift and increases stability & downforce at high speeds.
