Wilwood Right SRP Black Rotor, 14.25 x 1.10-inch, 72 Curved Vanes

This right-hand 14.25-inch SRP rotor uses a 1.10-inch friction width and directional drilling with face slots. Spec-37 iron and 72 curved cooling vanes support compatible street and moderate-temperature race systems, with the hat selected separately. Wilwood Engineering designs and manufactures disc brake systems from its base in Camarillo, California. Bill Wood founded the company in 1977; its range now includes calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized uses. Selection must account for the entire brake 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 1.10-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.
