Reduce drag on your race car with this innovative kit from Speedway. The Oil Bath Brake Rotor uses straight 30wt oil to lubricate the wheel bearings instead of grease, which significantly reduces friction. Oil can be easily changed using the supplied tapped plug.

You get (1) oil bath 10" hybrid rotor with races installed, 5/8" course thread quick-start studs, and (1) special O-ring dust cap (each rotor sold individually). Pre-drilled holes include 5 on 4-3/4" and 5 on 5" bolt circle spacing. 

  • Less Friction
  • Less Heat
  • Less Maintenance
  • Less Mess

NOT DESIGNED FOR ASPHALT RACING.
