Wilwood Disc Brakes Releases Starlite 55XD Lug-Drive Wide 5 Race Hubs

Rhea Sharma August 25, 2023 Press Release

Starlite 55XD Racing Hub with Lug-Drive Adapter

Wilwood Racing has engineered an innovative new Lug-Drive dynamic-mount rotor system specifically for the lighter, stronger Starlite 55XD Wide 5 hubs. The 55XD design shaves weight by mounting the forged aluminum rotor adapter closer to the hub’s reinforced center using fewer mounting bolts. The new Lug-Drive system simplifies rotor mounting using a snap ring in place of bolts and safety wire, allowing it to float and heat cycle without distortion for a more consistent pedal feel and longer life.

Lug-Drive Rotors for Racing Hubs

Drag and road race cars have long used Wilwood’s Lug-Drive system successfully, and the Wide 5 version was extensively tested in asphalt Late Model racing for over a year. The lighter, simpler attachment system allows rotors to stay flat and run truer, even at extreme temperatures. The Starlite 55XD is Wilwood’s latest lightweight evolution of their aluminum Wide 5 hub, available for traditional or Lug-Drive rotors. Currently, Lug-Drive Spec37 rotors are available separately in 11.75” x 0.81” with 40 symmetrical straight vanes or 11.75” x 1.25” with 48 directional curved vanes.

MSRP: starts at $344.08 (Hubs)

MSRP: starts at $212.99 (Rotors)
