The HSRA features American Production six-cylinder sedans with several safety enhancements. The driver’s high school colors and/or mascot must be incorporated into the paint scheme or design of the car. Students entering their freshman year of high school, current high school students as well as those just graduating from high school, with a minimum age of 14 and maximum age of 19 are eligible to compete. A complete set of rules and regulations can be found on the Official HSRA website at highschoolracing.org.
