Product details
This right-hand GT rotor combines a 1.25-inch friction section with 48 curved cooling vanes for an installation designed around an 11.75-inch disc. Its eight-hole attachment circle is 7.05 inches, a critical distinction from otherwise similar 7.00-inch mounting versions. 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.
