Product details
Wilwood's dynamic front hat uses a 1.750-inch offset and twelve rotor connections. Verify the bobbin system, hub register and flange clearance. Bill Wood established Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and builds disc brake systems for motorsport, street-performance and specialized uses, including calipers, rotors, master cylinders, valves, fittings and brake lines. Each part must match the requirements of the whole braking arrangement.

Fitment & Compatibility
This is a component for Matched dynamic brake systems, not a complete brake kit. Check the hub location, rotor mounting surface and caliper alignment as a system before ordering. Use the correct dynamic mounting hardware and rotor connection; an ordinary fixed-mount bolt set does not establish the specified floating assembly.
