NASA Super Touring Roadracing

NASA Super Touring (ST) is NASA’s premiere open marque racing series and an extension of the Performance Touring series, catering to more powerful and exotic cars. ST uses an Adjusted Weight to Power Ratio that starts with the vehicle competition weight and the chassis dynamometer horsepower numbers, and is modified and adjusted using ST Modification Factors. There are currently five ST classes, ST1, ST2, ST3, ST4, and ST5, with ST6 planned for 2019. ST encourages a wide range of builds and modifications within the power-to-weight confines to provide builders, tuners, and racers a showcase for their talent and imagination.

NASA Super Unlimited (SU) is the class available for any four wheel (non-formula) vehicles that have weight to power ratios or modifications over and above those permitted in Super Touring as well as those that do not fit in any other NASA class and are heavily prepared for serious speed. Performance modifications are unlimited, and the only restrictions are those pertaining to safety.


NASA ST racers receive championship points in their respective ST class within the region sanctioning the NASA racing event they are competing in. Certain multi-region events will be designated as “crossover events”, and the points earned by a driver at such an event will transfer to his or her respective home region’s championship series. However, a driver may also choose to simultaneously compete in more than one region’s championship series.  In that case, crossover event points will be applied to both series.  A driver must participate in a minimum number of event days to be eligible for championship series trophies, awards, or prizes at the end of the year (as determined by your region).  The points from every driver’s lowest events of the year will be dropped (number of event drop days will be determined by your region, and includes events that the driver was not present at).  Every year, there is a national Championship event, the NASA Championships, that takes place at various tracks across the country.  The eligibility requirement for the NASA Championships is that a driver must compete in at least 5 regional ST races.  Obtaining a certain minimum level of placing is not necessary.

Please contact your Regional ST Leader if you desire to compete, or if you just have questions.  You can find your Regional Leader’s contact form through the Contact button above, under Contact Us. You can also contact our National ST Director, Greg Greenbaum, on the same Contact Us page if you have national issues.  We have a great group of drivers, and although the majority of us are pretty competitive, our main goal is to have fun.  We often pit in the same area of the paddock, help each other out, and meet for Saturday dinner.  Whether you are new to competition, a current racer, or someone who has years of racing experience that wants a lower stress level competition, we have something for you.
