Product details
The Wilwood Golf front hat uses a five-hole flange and 0.410-inch offset. Match the actual brake conversion, 2.57-inch register and rotor circle. Bill Wood’s 1977 founding of Wilwood Engineering began a disc brake design and manufacturing business based in Camarillo, California. The range includes master cylinders, calipers, rotors, brake lines, valves and fittings for motorsport, street-performance and specialized vehicles. Component selection must consider the complete braking arrangement.

Fitment & Compatibility
Match this hat to the Wilwood front conversion installed on the Volkswagen Golf. The 2.57-inch register centers the component, while 0.410-inch offset locates the ring relative to the hub face. The five-on-3.93-inch hub-side clearance pattern and the eight-on-7.00-inch rotor connection serve different parts of the assembly. Confirm both interfaces and the rotor hardware.
