IMPORTANT NEWS
**All vehicles running with us need to meet the 100dB @ 50ft. sound limit imposed in 2011.**
For the 2012 Season, the MSCC will - with a few exceptions noted below - be using the SCCA's car classing scheme and the portion of their rules that deals with car classing. (Please note: MSCC is not a member of - or affiliated with - the SCCA. Their solo rules, which can be found here, are a copyrighted product of the SCCA.) You should probably take a look at the above link and see how the new classing affects your car.
So far, the exceptions to the SCCA rules are:
1) No tires below 140 treadwear allowed in stock classes.
2) Adoption of our old SMST classes.
3) An optional "Pro" class.
If you have any more specific classing questions, please contact Hien Nguyen
The 2011 MSCC rule book is available here. This rulebook is not, however, 100% inclusive; i.e. classing questions will still only be answered from the SCCA rules book.
