Product details
This SRP ring is the right-hand rotor named in the matching Wilwood rear-kit component lists. Its 36 straight vanes are non-directional internally, while the drilled-and-slotted face pattern determines the side-specific replacement within those kits. 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.
