Product details
A blank hat provides the starting point for the intended custom wheel-stud layout on this left-hand SRP rotor. The 12.19-inch ring and 7.24-inch internal parking drum are already machined as one casting, with a 1.910-inch hat offset. 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.
