Product details
This Wilwood front hub is machined for the solid-rotor offset arrangement used in selected Chevrolet brake assemblies. Its direct/adapter mounting configuration differs from the vented-rotor hub despite sharing the same two wheel bolt circles. Camarillo, California is home to Wilwood Engineering, founded by Bill Wood in 1977. The company designs and manufactures complete disc-brake systems and parts, from calipers and rotors to master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications. Selection depends on the complete brake-system configuration.
