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 3” to help reduce the amount of air going under the car and the splitter mounts with special rivet style nuts. With the new updated design there are no exposed fasteners for a cleaner appearance. The splitter also comes with holes for support rods (rods not included).
