Product details
The right-hand SRP pattern clears the pad contact area through drilling and face slots while retaining the integral rear parking drum. This 12.19-inch rotor is intended for the matching six-lug disc/drum arrangement, with a 0.81-inch friction section. Established in 1977 by Bill Wood, Wilwood develops its range around complete disc brake systems. The Camarillo, California manufacturer designs and manufactures calipers, rotors, master cylinders, valves, fittings and lines for motorsport, street performance and specialized applications. Installation geometry, pad selection and braking duty should be considered together when choosing this component.
