The Starlite Wide 5 “bubble” hub from Wilwood has been the standard in short track racing for over 40 years.
When building your race car’s brakes, it is the preferred foundation.
Combining three Wilwood innovations, the Starlite 55XD Lug-Drive hub creates a strong, light racing hub for the most demanding race tracks.
An evolution of Wilwood’s original lightweight Starlight II hub, the Starlite 55 series quickly became a benchmark.
With its five-bolt drive flange and Snap-Cap, the Starlite 55 is one of the strongest, lightest Wide 5 hubs, and the 55XD is even lighter.
The Starlite 55XD version reduces weight with just five rotor mount bolts at the hub’s reinforced center, which also reduces brake torque loading to the hub body.

Wilwood’s Lug-Drive dynamic floating rotor mount is a simpler, lighter system that eliminates rotor bolts, T-nuts, bobbins, and safety wire.
For years, drag and road race cars have used Wilwood's LugDrive system, and extensive testing has been done on top circle track cars over more than a season.

Starlite 55-XD hubs elevate performance and versatility for racing applications that require uncompromised strength without excessive additional weight.
At just over 7 pounds, the 55-XD Lug Drive achieves superior strength and modest weight through a highly efficient redesign of racing’s most popular wide 5 hub, the Starlight 55.
The 55-XD employs a bolt-on Lug Drive rotor mounting plate that adds overall strength by eliminating the brake torque loading from the main hub body and adding benefits of dynamic lug mounting rotors for less temperature induced deflection.
