Product details
The 12.88-inch SRP option adds drilling and slots to a heavy-wall Spec-37 ring. Its right-hand 48-vane core and 1.25-inch thickness must match the installed brake package, with the hat supplied separately. Founded by Bill Wood in 1977, Wilwood designs and manufactures disc brake systems in Camarillo, California. Its range includes calipers, rotors, master cylinders, valves, fittings and lines for motorsport, street performance and specialized applications. Rotor choice belongs within that complete system: the caliper, pad, mounting hardware and intended duty must work together.
