Product details
This Camaro hub uses one five-on-4.75-inch wheel pattern. The rotor hat is a separate component retained at the hub flange, so check the installed front conversion and spindle dimensions as a complete assembly. 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.
