Wilwood 140-14879 Rear Disc Brake Kit Corvette - FNSL4R 12.88 C4

The Wilwood FNSL4R rear race brake kit delivers high-capacity braking performance for dedicated track use on 1988-1996 C4 Corvette rear suspensions and purpose-built vehicles. This competition-focused system eliminates the parking brake and replaces the original single-piston caliper with a high-efficiency forged aluminum Superlite four-piston radial mount caliper.

Key Features:

• Forged narrow Superlite four-piston radial mount calipers with Type III Mil-Spec hard anodized finish in medium gray
• Stainless steel pistons with internal damping springs and controlled retraction for consistent performance
• High-temperature seals designed for extreme duty use and long-term durability
• 12.88-inch diameter Spec37 alloy directional vane GT series rotors in weight-saving two-piece construction
• Forged aluminum rotor hats mount directly to OE hubs
• High-friction endurance race compound brake pads for sustained high-temperature competition
• Caliper piston volume matched to OE Corvette master cylinder output
• Compatible with balance bar manual brake pedals in purpose-built race vehicles

The hard anodized finish provides superior wear resistance in piston bores and exceptional protection against abrasion and corrosion. This complete rear brake system is engineered for smooth driver control, high brake torque, and extended pad life during sustained competition use.
