Product details
This Cadillac front hub is single drilled on a five-on-five wheel circle. It supports a separate rotor plate and requires the specified press-on bearing cap in addition to the correct spindle bearings. Wilwood Engineering’s work covers the design and manufacture of disc brake systems for motorsport, street-performance and specialized applications. Bill Wood founded the company in 1977 in a business now based in Camarillo, California. Its calipers, master cylinders, brake rotors, brake lines, valves and fittings must be selected around the complete system.
