Forged Superlite 4R Big Brake Rear Brake Kit (Race)

Forged Narrow Superlite 4R-QS caliper rear road race kits provide matched performance in conjunction with FSL6R and Aero6 front race kits on vehicles built specifically for competition. FNSL4R-QS calipers use high temperature, fluid resistant high gloss “Quick-Silver” finish, stainless steel pistons to retard heat transfer from the pads and high temperature seals for reliability in sustained high heat. Radial mount brackets attach the caliper in the stock location. GT series directional vane competition rotors are dynamically mounted to forged aluminum hats. Kits also include high temperature, high friction race compound pads and all premium grade fasteners.
