Product details
A smooth HP friction face and 32-vane iron construction make up the service-brake portion of this rear rotor. Its integrated six-lug hat also provides the parking-brake drum, with a 1.910-inch offset specific to this 12.19-inch configuration. System compatibility is central to choosing a replacement rotor, including its relationship to the caliper, pad and mounting hardware. Wilwood designs and manufactures disc brake systems in Camarillo, California, offering calipers, rotors, master cylinders, valves, fittings and lines across motorsport, street performance and specialized applications. The company was founded in 1977 by Bill Wood.
