Wilwood Right Heavy-Wall SRP Rotor, 14.25 x 1.25-inch, Black Drilled and Slotted

The wider 1.25-inch section makes this right-hand SRP rotor a different fit from the 1.10-inch version of the same diameter. Its heavy-wall Spec-37 casting carries 72 curved vanes, with drilled and slotted faces for compatible street and moderate-heat applications. Based in Camarillo, California, Wilwood Engineering was founded in 1977 by Bill Wood to design and manufacture disc brake systems and components. Its calipers, brake rotors, master cylinders, valves, fittings and brake lines serve motorsport, street-performance and specialized applications. Rotor selection is therefore a decision about the whole brake system and its mating parts.

Fitment & Compatibility

This ring is a component of a matched brake system. Confirm 1.25-inch rotor clearance through the caliper, the 14.25-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.
