Product details
The HPS version introduces GT face slots to the six-lug 12.19-inch rear disc/drum rotor. Its cast-in hat retains the 1.910-inch offset and 7.24-inch parking-brake drum, allowing selection by the established assembly geometry. Wilwood began in 1977 with founder Bill Wood and is based in Camarillo, California, where it designs and manufactures disc brake systems. Calipers and rotors sit alongside master cylinders, valves, fittings and lines in a range serving motorsport, street performance and specialized applications. Selecting these parts together is essential to a correctly matched brake installation.
