Product details
This right-hand SRP rear rotor includes a hat drilled for three wheel-stud clearance circles. Its 12.19-inch friction ring is cast with a 1.910-inch-offset center and 7.24-inch parking drum, defining the complete geometry of the replacement. 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.
