The Thunder Roadster Series was created in 2009 in NASA’s Southeast Region for spec Thunder Roadsters with strict regulations limiting modifications to only safety equipment and reliability for longer road racing events.
The Thunder Roadster design is based on a 1964 Watson Indy roadster built by US Legends Cars. The cars feature a vintage look built on tube frame chassis with spec Hoosier tires, and a 12.3 horsepower-to-weight ratio to contain costs without limiting performance potential.
