Product details
These Wilwood aluminum rings center a brake rotor or hat on a 2.877-inch hub or axle register. The pair fits the matching 3.060-inch counterbore, with the full ring profile determining how it seats. The manufacturer, Wilwood Engineering, was established in 1977 by Bill Wood and is based in Camarillo, California. It produces disc-brake systems and the calipers, rotors, master cylinders, valves, fittings and lines used within them. Motorsport, street-performance and specialized applications each require a suitable combination of those components.
