APR Performance Splitters aren't just an aesthetic piece but also fully aerodynamically functional. The Carbon Fiber Front Wind Splitter covers the entire area under the bumper and provides a flat protrusion past the front end. This creates a high pressure area on top of the wind splitter and a lower pressure underneath it. This reduces the effect of lift and helps the driver gain extra traction and control. Supporting every ARP Splitter are adjustable Stainless Steel Rods.
