MAC is part of the Metropolitan Council of Sport Car Clubs. We adhere to their rules for our competition events. The Met Council competition rules are updated annually and define the rules for all Met Council autocross competition events. You can view and download the rules at: http://www.met-council.org/rules.htm. These competition rules refer to the SCCA Solo rules for classing and safety details.
For indexed classes, we use the PAX/RTP factors developed by Rick Ruth. These are updated annually based on results from regional and national events from around the US.
MAC adds some supplemental rules to the core Met Council rules. We update the supplemental rules annually and post them to the Met Council rules page.
