Product details
This smooth-face HP rear rotor carries a deeper 2.320-inch-offset hat and a 3.06-inch center register. Its 12.19-inch ring is vented through 32 vanes and cast with the 7.24-inch parking-brake drum required by the matching disc/drum system. Founded by Bill Wood in 1977, Wilwood designs and manufactures disc brake systems in Camarillo, California. Its range includes calipers, rotors, master cylinders, valves, fittings and lines for motorsport, street performance and specialized applications. Rotor choice belongs within that complete system: the caliper, pad, mounting hardware and intended duty must work together.
