Product details
Eight threaded mounting points attach this left-hand Ultralite ring to its intended hat or hub. The 12.19 x 1.25-inch iron casting uses a 32-curved-vane core and plain faces, preserving the geometry of the matching thick-rotor package. Founded in 1977, Bill Wood’s Wilwood is based in Camarillo, California and designs and manufactures disc brake systems for motorsport, street performance and specialized applications. Its range runs from calipers and rotors to master cylinders, valves, fittings and lines. Choosing a rotor involves matching those surrounding components as well as the vehicle’s intended use.
