Product details
The integral hat eliminates a separate bolted rotor ring in this 12.88-inch right-hand SRP configuration. Its 1.75-inch offset and dual five-lug clearance circles must match the actual hub and caliper placement. The manufacturer is Wilwood Engineering of Camarillo, California, founded by Bill Wood in 1977. It designs and manufactures disc brake systems, supplying calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. Matching this component requires consideration of the complete brake system.

Fitment & Compatibility
Front replacement for the corresponding 12.88-inch Superlite conversion, including the Wilwood ProSpindle system in DS-869. Check the conversion's hub and bracket arrangement as well as the 1.75-inch hat offset. Its dual five-lug clearances do not identify a direct-fit stock vehicle application.
