Wilwood Left 14.25-inch SRP Rotor with 1.25-inch Heavy Wall and Black Finish

This left-side SRP friction ring has the heavier 1.25-inch section and 14.25-inch outside diameter. The separate hat interface uses twelve holes on an 8.75-inch circle, so a matching wheel bolt pattern alone cannot establish fit. Disc brake systems and components are the work of Wilwood Engineering, founded by Bill Wood in 1977 and based in Camarillo, California. The company designs and manufactures calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications, with each component selected to match the complete system.

Fitment & Compatibility

Installation requires a hat or hub designed for the 8.25-inch rotor register and 12 x 8.75-inch attachment. Verify wheel clearance around the complete caliper, along with the rotor's 1.25-inch width. The ring alone does not define a direct-fit vehicle or axle application. 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.
