Stillen Front Splitters

Front splitters usually sit in the lowest forward location on your vehicle, making them vulnerable to encounter road debris, curbs, and driveways, causing damage to the splitter. Stillen manufactures a large variety of vehicle-specific front splitters offering not only aerodynamic benefits for your car, but also sporty style, and each one is made from Stillen's proprietary polyurethane, which is flexible and durable enough to hold up to street use. They are carefully measured and shaped to match the vehicle and come either ready for prep and paint or with a paintable matte black finish. Select the Stillen front splitter designed for your car.
