Product details
The solid-rotor version of this Wilwood front hub establishes the mounting geometry for an adapter-based GM G-Body brake assembly. It retains the dual five-lug wheel pattern while using a different brake offset from the vented-rotor hub. Bill Wood founded Wilwood Engineering in 1977; the company is based in Camarillo, California. Wilwood designs and manufactures disc brake systems, from calipers and brake rotors to master cylinders, valves, fittings, and brake lines. Its motorsport, street-performance, and specialized components are chosen to suit the complete braking installation.
