The FormaCars 9 piece rub rail kit for the Factory Five 818 is CNC machined black UHMW which is tough and slick. It starts at the front of the main chassis and wraps around both sides, extending to the rear wheels. Each piece attaches with 3-4 self threading screws (the kit includes enough for 4 per piece) and the properly sized drill bit for those screws is included.
It’s easy to install no matter if your car is still in pieces or already complete. And in true FormaCars fashion, everything you need is in the box, and ground shipping is free. It’s good protection for your bottom side
