Wilwood Right SRP Rotor, Black 14.00 x 1.25-inch, Twelve on 8.25-inch Mount

This right-hand 14.00-inch SRP ring uses the 8.25-inch mounting circle and 7.75-inch register. Its heavy-wall 1.25-inch section and black drilled-and-slotted face require the matching hat and caliper, not the larger-circle components used on other 72-vane rotors. Founded by Bill Wood in 1977, Camarillo, California-based Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Its calipers and brake rotors work alongside its master cylinders, valves, fittings and brake lines, with each individual component selected according to the complete system's requirements.

Fitment & Compatibility

The 1.25-inch working width must suit the caliper, while the hat centers the ring on its 7.75-inch register. Check the 12 x 8.25-inch attachment and radial pad coverage before installation. Vehicle make or wheel pattern alone cannot identify a replacement rotor ring. 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.
