Wilwood Right HD Rotor with 13.06-inch Diameter, 1.25-inch Width and Plain Faces

This 13.06-inch HD version uses the larger friction diameter while retaining the 1.25-inch section. Its right-hand 48-vane casting is balanced and plain-faced, with the familiar twelve-bolt interface requiring the correct radial caliper position. Bill Wood established Wilwood Engineering in 1977; the company is based in Camarillo, California and designs and manufactures disc brake systems. Calipers, brake rotors, master cylinders, valves, fittings and brake lines form its range for motorsport, street-performance and specialized applications. Compatibility depends on selecting those parts for the requirements of the complete brake system.

Fitment & Compatibility

Select the separate hat for the 12 x 8.75-inch rotor-attachment pattern and 8.25-inch register. The 13.06-inch friction diameter and 1.25-inch section must agree with caliper placement and pad sweep. This mounting circle is independent of the vehicle's wheel-stud pattern. Select pads and operating duty to suit the rotor material and the intended brake system.
