Product details
This hat-mounted Camaro hub uses a 1.760-inch N reference rather than the 1.630-inch value on another version for the same years. The complete hub and hat geometry must agree with the installed front conversion. Wilwood Engineering designs and builds disc brake systems in Camarillo, California. Bill Wood established the company in 1977; it supplies brake rotors, calipers, master cylinders, valves, fittings and lines for specialized applications, street performance and motorsport. The complete brake system determines which individual components are appropriate.
