Product details
Factory burnishing adds a preparation treatment to this compact 0.81-inch GT ring. Its 40 straight vanes and slotted faces retain non-directional operation, but the eight-lug center still requires the correct snap-ring carrier. 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.

Fitment & Compatibility
