What is the minimum helmet rating for drag racing? I'm not looking for the differences in ratings or the differences in helmets. Just the minimum rating accepted for drag racing events. Anyone know? The track I go to is Orlando SpeedWorld, but I'd like to be able to use it at any track here in Florida. I imagine any NHRA approved helmet will do, but don't know the minimum rating. Can I use a Snell M2000 even though it's designed for motorcycles? I don't plan on going any faster than 12's with this car.
