Wilwood Front HP Rotor and Hub for Mustang 1970–1973, Plain 11.29-inch Iron

The later Mustang hub configuration is the key distinction of this 11.29-inch front rotor. Its 0.94-inch friction width and five-on-4.50-inch wheel pattern do not eliminate the need to match the 1970–1973 spindle and conversion hardware. Wilwood Engineering designs and manufactures disc brake systems from its base in Camarillo, California. Bill Wood founded the company in 1977; its range now includes calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized uses. Selection must account for the entire brake system.
