SCCA Rules


Handling Adjustments

Autocross 101

Novice Handbook

Autocross is a driving skill event over a short, miniature road course clearly defined using traffic cones. Each vehicle is timed individually as it negotiates a course that puts the emphasis on driver skill and vehicle handling using time as a means to measure proficiency. The skills learned and practiced here; smooth transitions, enhanced braking and skid correction have an immediate impact on your driving skills and will translate into safer street driving.

Current Class Champions

The rules and guidelines cover participant, site, safety and vehicle capabilities. They are a result of this club’s 50+ years of experience and the experiences of many similar clubs from all around the country. There are course standards that must be met to protect the participant, the facility and the neighborhood. All cars must pass a safety inspection. SCCNH sanctioned events are conducted under the watchful eyes of Safety Stewards insuring autocross to be one of the safest motorsports.

The events are low-keyed, with the emphasis on fun. Instructors are available to assist and ride along with novice drivers or any driver who feels they could use some improvement. Each season one or two beginner autocross schools are held where you can learn how to autocross with instruction from our experts. Autocross is an opportunity to test the handling ability of your car and your capability as a driver in a controlled environment.

Results & Awards

Event results will be here within one week (usually within a day or so) following the event. Click the Results button at the top of this page.

The top three positions in each class will be awarded dash plaques denoting their position.

We keep track of the points that you accumulate throughout the year based on how you place at each event. This is kept track by your number. Therefore it is important that you use the same number and SCCNH class. If you are going to run in a different SCCNH class you need a different number. However, if you change SCCA classes but remain in the same SCCNH class you can use the same number. Starting at first place in class you get: 10,8,6,5,4,3,2 and everyone else gets 1. We count your best seven of the eight events. At the end of the year, SCCNH members receive awards based on placing in the top three positions of each class.

We run seven (7) classes that are all indexed using the PAX/RTP modifiers. This Index was developed by Rick Ruth and reflects study of results from well over 500 nationwide Solo events including, the Solo National Championships, National Tour, Alabama Region, many SCCA regions and many independent clubs like ours. This system is meant to allow different classes of cars to run together and be competitive. Your time is modified by multiplying it by the PAX/RTP index for your SCCA class. In theory this would allow a Honda Fit to fairly compete with a Porsche GT3.

Five of our classes are based on the types of vehicles that generally come to our events and are designed to group cars with similar modifications together. The objective is to get eight to twelve vehicles in each class.

The Stock Performance class is for most sports cars and high performance sedans and coupes.

The Stock Sedan class is mostly family sedans and coupes.

We get a lot of vehicles that have been modified but are still street able. Most fall into what SCCA calls Street Touring and Street Modified and therefore we created those classes.

All remaining vehicles go into our Race class.

The Novice class is open to drivers that have not been racing; including autocross, solo, HPDE and hillclimb; in the past 20 years and are driving a street car (regisered) with street tires (wear rating of 140+).

The Ladies class requires six or more ladies that want to run by themselves. They must declare that they want a Ladies class on the day of the event.
