Product details
The left-hand surface and vane orientation define this SRP ring for the corresponding side of a 14-inch assembly. Its 1.25-inch Spec-37 section is paired with a 72-vane core and black-finished casting. Camarillo, California is home to Wilwood, founded by Bill Wood in 1977. The company designs and manufactures disc brake systems for motorsport, street performance and specialized applications, supplying rotors, calipers, master cylinders, valves, fittings and lines. Matching the rotor to the complete assembly matters as much as selecting its diameter or surface treatment.
