Wilwood Left SRP Heavy-Wall Rotor with Twelve-Bolt Flange, Black 15.00 x 1.25-inch

The left-side SRP rotor combines a 15.00-inch diameter with the heavier 1.25-inch friction section. Its directional drilled-and-slotted face is suited to the matching moderate-temperature application, while black electrocoat protects the iron outside the swept surface. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and manufactures disc brake systems, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Its motorsport, street-performance and specialized components are selected around the requirements of the whole braking system.

Fitment & Compatibility

For the left side of the matched fifteen-inch SRP brake. The twelve fasteners on the 8.75-inch circle and 8.25-inch registration locate its 1.25-inch friction section relative to the caliper. Limit the drilled-face selection to the appropriate street or moderate-temperature race duty and verify the pad compound for that use.
