Wilwood Right-Hand 11.75-Inch SRP Ring, 32-Vane Iron with Black Electro-Coat

This right-hand SRP ring combines an 11.75-inch drilled-and-slotted face with a 32-vane iron core. Its 0.81-inch section and eight-hole mounting flange make it a specific alternative to the plain HP ring in a compatible assembly. Disc brake systems have been Wilwood’s focus since Bill Wood founded the company in 1977. Based in Camarillo, California, Wilwood designs and manufactures calipers, rotors, master cylinders, valves, fittings and lines for motorsport, street performance and specialized applications. The rotor is one part of that system and needs compatible pads, calipers and mounting components.
