Product details
The Wilwood C6 front hat has a 0.36-inch mounting face and 0.290-inch offset. Verify the 2.78-inch register and twelve-bolt rotor ring. Disc brake system design and manufacturing are Wilwood Engineering’s focus. Bill Wood founded the Camarillo, California company in 1977; its range spans brake rotors, master cylinders, calipers, fittings, valves and brake lines for motorsport, specialized and street-performance applications. The choice of individual components depends on the complete brake system.

Fitment & Compatibility
Use this shallow hat only in the C6 Corvette front package that specifies it. The 0.290-inch offset and 0.36-inch face thickness both affect rotor location, and its 2.78-inch register must seat on the intended hub. The listed flange clearances do not change the vehicle's wheel-stud pattern. Match the twelve-bolt friction ring and check the complete caliper envelope.
