The Street Front Splitter is made from ¼” Aluminum Composite Material (ACM). ACM is used for its high quality smooth finish and superior rigidity compared to ABS Plastic. The splitter has vertical trim piece that lowers the splitter approximately 2.5” with a 2.5" lip to help reduce the amount of air going under the car. Mounting hardware is included. Support Rods are not required for installation on the street version, but can be added if so desired.
