Product details
This left-side Ultralite ring combines plain iron faces with a directional 32-vane casting. The 11.75 x 1.25-inch geometry and eight-hole flange make it a replacement for the corresponding complete brake assembly, not a universal rotor blank. Since its founding by Bill Wood in 1977, Wilwood has designed and manufactured disc brake systems from its base in Camarillo, California. Its products span rotors, calipers, master cylinders, valves, fittings and lines for motorsport, street performance and specialized applications. Brake selection should account for the whole installation, including mounting dimensions, friction materials and hydraulic balance.
