Forged Narrow Superlite 4R caliper rear road race kits provide matched performance in conjunction with FSL6R and W6AR front race kits on vehicles built specifically for competition. BSL4R calipers use 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 provide high efficiency cooling and mount to the drive axles with forged aluminum hats. Kits also include high temperature, high friction race compound pads and all premium grade fasteners.
