RTR Unpainted Fiberglass Spec 5 Wide Body Kit for 2018-2023 EcoBoost and GT Mustangs.
RTR’s Fiberglass Spec 5 Wide Body Kit is the best way to give an aggressive and wider look to your S550 Mustang when hitting the track. This body kit features a full lightweight fiberglass construction and offers excellent wind rigidity during high-speed applications. The kit widens the front and rear fenders, 50mm and Rear Fender 75mm, so you can bolt on a wider staggered wheel setup for better traction off the line. A smooth gel top finish is applied to the unpainted body kit, making it highly receptive to color-matching paint.
