Product details
A left-hand SRP face pattern and 1.10-inch nominal thickness define this 14-inch replacement. The 72-vane Spec-37 casting has a 10.00-inch far-side opening and an 8.25-inch mounting register, both of which must clear the intended hat and hub. A well-matched brake installation starts with compatible components. Wilwood designs and manufactures disc brake systems that include calipers, rotors, master cylinders, valves, fittings and lines, serving motorsport, street performance and specialized applications. Bill Wood founded the company in 1977 in Camarillo, California; this rotor should be evaluated as part of the complete braking package.
