Our local region uses the Sports Car Club of America Solo National Rules and classing with the following exceptions:


Most cars are classed in the SCCA Solo rule book based on modifications. You can find a cheat sheet HERE. Once you know your category you look up your vehicle by make/model to determine your class using Appendix A of the rulebook. This is your primary class. If you have any questions, you can email for help.

Due to being a smaller region several classes are merged in to similar PAX groups. By look at the list below you can see which PAX group your vehicle falls in when registering. What is PAX? Check out Novice Questions Thread.

Event Scoring
The position you finish in determines how many points you get towards the season and the end of year trophies. Points are given for finishing places using the following:
1st: 10 points
2nd: 7
3rd: 5
4th: 3
5th: 2
6th and below: 1

End of Year Trophy Rules (Except Pro and Novice)
Season points are determined by using the best 10 scoring events a driver sets. In the event of a tie, both drivers will share that position in the results, there are no tie breakers. You must compete in a minimum of 6 events and you cannot trophy in more than one class for a season trophy. Driver must be a full SCCA member (not weekend member) by the date of the last event of the year to be eligible for a trophy. 

Pro Class Rules
Only the first 3 runs count for points to prepare these drivers for the pressures of national and pro events. End of year season points only use the top 7 best race points.

Novice Class Rules
New to autocross? This is the group for you! By being in novice class we ask that you put a “N” on your car. It lets us know that you are new and may need additional assistance. We also require you have an instructor ride with you on your first 3 runs at every event. That gives you feedback to drive better and faster while insuring you stay safe and don’t get lost. New drivers can be in the Novice class all year but are strongly encouraged to move out of it after their first year. If you don’t feel ready to leave the class or joined late in the year, that’s okay! You can continue to race in Novice the next year. For season points and end of year trophy Novice is unique. Your event points are not based on what place you got, but what your PAX score is (a number from 0 to 1000 based on the best time you ran). The best 3 PAX scores you got over the year will be used to determine your position in the novice class with the winner getting the Novice of the Year trophy. To qualify you do not need to be a SCCA member, but you must attend at least 5 events.
