Our region has always allowed M-rated helmets for tracdk use, however, if you're buying one I would 100% recommend an SA helmet. It's especially important for people with roll bars or cages int heir cars, as the difference between M and SA helmets is that M-rated helmets are designed to disappate a single massive impact, while SAs are supposed to withstand multiple smaller impacts from banging your head against your roll bar repeatedly in a rollover.
