WE DESIGN AND MANUFACTURE SPLITTERS FOR MODERN MUSCLE CARS. We use solid, 1/4" Automotive ABS to make all of our splitters. ABS is light, flexible, yet extremely durable (same product Ford Performance uses on their 12-13 Boss 302 Leguna Secas, Boss 302Ss & 302Rs, and FR350s. Both front and side splitters actually create downforce that helps keep your car planted at higher speeds and they give your ride a unique custom look.
