Street Tire Open (STO)

Street Tire Open is a class created by the Kentucky Region. It is designed for drivers who have made modifications to their cars, but not specifically prepared for a SCCA® national class like Street Mod. This class is designed as a level playing field for the casual racer who just wants to come out and have a fun time. Because this class isn’t recognized by at the national level the KYSCCA uses a PAX multiplier 1.0 and makes it uncompetitive for driver of the year. Any vehicle can compete in STO as long as it meets the following rules.

  • The vehicle must meet the eligibility requirements outlined in section 3.1 of the SCCA® National Solo® Rule Book.
  • The vehicle must meet the safety requirements outlined section 3.3 of the SCCA® National Solo® Rule Book.
  • The vehicle must have tires that meet the rules outlined in section 13.3 of the SCCA® National Solo® Rule Book.
  • The vehicle cannot be an “open wheeled” car. IT MUST HAVE FENDERS.
