Product details
The 2.320-inch hat offset is the key starting point when matching this plain-face HP rotor to a disc/drum brake assembly. Its 12.19-inch diameter and 0.81-inch thickness surround a 7.24-inch parking drum, with five-hole wheel-stud clearances for two bolt circles. Disc brake systems have been Wilwood’s focus since Bill Wood founded the company in 1977. Based in Camarillo, California, Wilwood designs and manufactures calipers, rotors, master cylinders, valves, fittings and lines for motorsport, street performance and specialized applications. The rotor is one part of that system and needs compatible pads, calipers and mounting components.
