Not to hijack here, but the helmet differences are that the "m" helmets are motorcycle helmets and as such are not fire retarded, and the "sa" or special application helmets do have a fire rating. Fire rated helmets are required when driving suits are required, which is in the wheel to wheel racing events, but seldom in the DE drivers ed events..
What are the passing rules in the "A" group ? Are all types of cars allowed ? RacerAl are you going ?
