COMPETITION Classes

* All classes are required to display proportional sized numbers on each door, and the roof/wing of the vehicle. This not only increases racing realism, but also enhances the race director’s ability to make sure each car is counting correctly, and provide accurate running order announcements during the race.

Thank you for your cooperation in making the racing experience at Checkered Flag Raceway the best it can possibly be!
