Product details
The right-hand SRP pattern adds drilling and slots to this six-lug rotor and hat. Its 1.52-inch offset locates the 12.19-inch friction ring, with the 1.10-inch width and center register checked against the intended conversion. Wilwood Engineering is based in Camarillo, California and was founded by Bill Wood in 1977. It designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. The range covers calipers, brake rotors, master cylinders, valves, fittings and brake lines, all of which require selection around the full brake system rather than an isolated dimension.
