Wilwood Left Black 14.00-inch SRP Rotor, 1.25-inch Width and 8.25-inch Attachment

The left-side SRP rotor in this family shares a 14.00-inch diameter with several other Wilwood rings, but uses the smaller 8.25-inch attachment circle. Black electrocoat covers the heavy-wall Spec-37 casting around its finished contact faces. Wilwood Engineering is based in Camarillo, California and was founded by Bill Wood in 1977. It designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. The range covers calipers, brake rotors, master cylinders, valves, fittings and brake lines, all of which require selection around the full brake system rather than an isolated dimension.

Fitment & Compatibility

For an assembly designed around a 14.00 x 1.25-inch friction ring. Use the correct rotor fasteners and hat, checking both the 12 x 8.25-inch attachment circle and the 7.75-inch registration. Determine axle suitability from the complete brake kit, not from the rotor's diameter. 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.
