Grand Nationals

Ultimate RaceCars builds new cars and will service and repair any brand chassis.

  • Chassis Fabrication and Repair
  • Bodies / Interiors
  • Setup from simple scaling to complete front and rear geometry updates (any chassis make)

Ultimate RaceCars Grand National chassis are based on the GM metric G-body frame and made to Grand National or Mid-American rules. Only high quality DOM tubing is used throughout for a stronger chassis. As with all URC chassis these cars are built to reduce chassis flexing to provide a consitent and fast racecar.
