Wilwood Front Camaro (2010–2018) Lug-Drive Hat for a 7.77-Inch Rotor Interface

Twelve drive lugs on a 7.77-inch circle connect this Wilwood Camaro front hat to its rotor. Match 0.920-inch offset and the snap-ring retention system. 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

This is a component for Chevrolet Camaro 2010–2018 brake conversions, not a complete brake kit. Check the hub location, rotor mounting surface and caliper alignment as a system before ordering. Use the specified lug-drive friction ring and clip/snap-ring retention system. A conventional bolt-on ring is a different attachment arrangement.
