Product details
A four-on-4.25-inch wheel flange identifies this Sunbeam Tiger front hub. The hub works within the documented hat-mounted brake conversion, using the specified bearings and separate rotor hat. Disc brake system design and manufacturing are Wilwood Engineering’s focus. Bill Wood founded the Camarillo, California company in 1977; its range spans brake rotors, master cylinders, calipers, fittings, valves and brake lines for motorsport, specialized and street-performance applications. The choice of individual components depends on the complete brake system.
