Forged Narrow Superlite 4R Big Brake Rear Brake Kit (Race) Description
FNSL4R rear race kits provide high capacity braking for dedicated track use on Corvettes and other purpose built vehicles equipped with 1988-1996 C4 Corvette rear suspension. The parking brake is eliminated and the original equipment single piston combination caliper is replaced with a high efficiency, forged aluminum, fixed radial mount narrow four piston Superlite caliper. The forged caliper bodies feature a Type III Mil-Spec, medium gray color hard anodized finish. Hard anodizing provides superior wear resistance in the piston bores and high resistance to abrasion and corrosion throughout. Stainless steel pistons with internal damping springs are used with controlled retraction, high temperature seals for long term durability and consistent performance during extreme duty use. The caliper piston volume is fully compatible and matched to the output of the OE master cylinder on production based Corvettes, and easily configured with balance bar manual brake pedals in non-OE based purpose built race vehicles. The calipers are coupled with weight-saving two-piece rotor assemblies using 12.88” diameter Spec37 alloy direction vane GT series rotors mounted to the OE hubs with forged aluminum hats. High-temperature, high friction, endurance race compound brakes pads are specifically selected per application to provide high brake torque with smooth driver control and long wear in sustained high temperature competition.
