Wilwood Starlite 55XD Rear Hub 5-Bolt Wide 5 5/8-11 Studs 8x7 Rotor Mount 270-12111C

If you're running a dedicated race car with a Wide 5 wheel bolt pattern, you need a rear hub engineered to handle serious brake loads without deflection or flex. The Wilwood Starlite 55XD delivers that precision with a bolt-on rotor mount that transfers brake torque directly to the strongest section of the hub, eliminating the weak points that cause fade and inconsistent stopping power. At just 7.4 pounds, you get race-proven strength without the weight penalty.

This hub is built from high-density aircraft aluminum with a black E-coat finish, meaning it resists corrosion in both street and track environments while maintaining tight tolerances lap after lap. The dynamic adapter mount and included 5/8-11 press-in studs make installation straightforward for shops familiar with hub work, and the 8 x 7.00-inch rotor bolt circle pairs seamlessly with Wilwood's extensive rotor lineup.
