Product details
Honda rear conversions using this Wilwood hat need an 8 x 7.00-inch rotor circle. Compare the 0.750-inch offset and four-hole hub flange. The manufacturer, Wilwood Engineering, was established by Bill Wood in 1977 and is based in Camarillo, California. It designs and builds disc brake systems with a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Motorsport, street-performance and specialized applications require components selected for the complete braking system.

Fitment & Compatibility

Select the rotor and attachment hardware separately for the documented assembly. Follow the installation drawing for engagement and clearance at every mounting point.
