BRG Rules
Autocross Classes
We will be using current SCCA classes, which are divided into the following categories:
- Street
- Street Touring
- Street Prepared
- Street Modified
- Prepared
- Modified
- Kart
These categories are then divided into class depending on the model and year car you have and what modifications have been done to the car.
Competition Divisions
NOVICE – First time in autocross competition (for 2 years)
INTERMEDIATE – For less experienced drivers or cars not prepared at top level. No time limit for this class.
PRO – This a category that is reserved for drivers that have demonstrated very strong driver skills and experience (not to be judged in years), excellent car preparation and/or possess a vehicle that has a distinct and clear advantage over the competition due to its power, weight, tire & wheel size, car classification and/or PAX Index.
Number of Runs
We may have a total of 5 to 8 runs per event depending on the number of entries and any time constraints.
What is the cost?
The cost is $60 for all entrants.
Point System
1st-25; 2nd-18; 3rd-15; 4th-12; 5th-10; 6th-8; 7th-6; 8th-4, 9th-2; 10th-1.
Car Numbers
Competitors are encouraged to bring their own numbers and letters. Blue painter’s tape will be available for making your own numbers and class letters. Numbers must be at least 8″ tall with a 1.5″ stroke in a contrasting color.
PAX Index
PAX stands for “Professional Autocross.” It is a handicapping system developed by Rick Ruth many years ago to equalize the times across the myriad of classes developed by the SCCA. Each car class will have a PAX index, or multiplier for each car’s raw time. A new index is updated every year by analyzing local and national level autocross events across the U.S.
For example, A Modified (AM) is the fastest class and has a PAX index of 1. The slowest class is H Street (HS), which has a PAX index of 0.780. Theoretically, the PAX times for these two cars can be compared in competition and a winner determined even though they are in vastly different classes.
