Wilwood 140-16208 Forged Narrow Superlite 4R Big Brake Rear Kit (Race), 13.00in — Corvette C5/C6

Wilwood 140-16208 Forged Narrow Superlite 4R Big Brake Rear Kit (Race)

Forged Narrow Superlite 4R/ST four-piston radial-mount race caliper rear kits are the engineered match for the AERO6R/ST front race kits on Corvettes intended for unrestricted road race competition. Emphasis is on matched front-to-rear balance, high durability, and efficient heat management without adding unnecessary rotating or unsprung weight to the driveline and rear suspension. FNSL4R/ST calipers use a forged aluminum body with a Type III Mil-Spec, medium gray hard anodized finish for superior wear resistance. Thermlock® pistons reduce heat transfer from the pads to increase fade resistance and extend service life.

Spec-37 alloy GT series directional vane 13.00in rotors are dynamically mounted using Wilwood’s Dynamic Lug Mounting system to forged aluminum hats, hard anodized for superior wear resistance. Mounting brackets, including all premium-grade fasteners, secure the calipers to the uprights in the stock location with no modifications required. This championship-proven system is completed with high temperature, high friction race compound pads selected by application. Requires the separate purchase of a stainless steel braided flexline kit ordered according to model year.
