Wilwood Left SRP Rotor, Black 13.00-inch Spec-37 Ring with 1.10-inch Width

This left-hand SRP ring uses a 6.38-inch register within its twelve-bolt mounting interface. The 13.00 x 1.10-inch friction envelope and black drilled-and-slotted surface should be matched to the existing assembly as a complete set of dimensions. Camarillo, California is home to Wilwood Engineering, founded in 1977 by Bill Wood. The company designs and manufactures disc brake systems and their calipers, brake rotors, master cylinders, valves, fittings and brake lines. Across motorsport, street-performance and specialized applications, these components must be matched as parts of a complete braking system.

Fitment & Compatibility

This ring is a component of a matched brake system. Confirm 1.10-inch rotor clearance through the caliper, the 13.00-inch radial envelope and the separate hat's 12 x 7.00-inch attachment. Its 6.38-inch registration must locate concentrically on the specified mounting hardware. 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.
