Wilwood Right SRP Rotor, Black 12.88 x 1.10-inch Spec-37 with 48 Curved Vanes

The 1.10-inch section places this right-hand SRP ring between other widths in the 12.88-inch range. Its black-coated Spec-37 construction combines 48 curved vanes with the directional drilled-and-slotted face treatment. Bill Wood established Wilwood Engineering in 1977; the company is based in Camarillo, California and designs and manufactures disc brake systems. Calipers, brake rotors, master cylinders, valves, fittings and brake lines form its range for motorsport, street-performance and specialized applications. Compatibility depends on selecting those parts for the requirements of the complete brake system.

Fitment & Compatibility

This ring is a component of a matched brake system. Confirm 1.10-inch rotor clearance through the caliper, the 12.88-inch radial envelope and the separate hat's 12 x 8.75-inch attachment. Its 8.25-inch registration must locate concentrically on the specified mounting hardware. Wilwood specifies the SRP face treatment for street and moderate-temperature race duty; severe sustained racing calls for evaluation of the corresponding HD or GT option.
