I guess a box aint not good then.
I have a snell approved helmet it is an international standard if it has an M precceding the year it is for motorcycle use which is what most of us use the only difference is that the motorcycle helmet does no do the fire test which is rather an important point given that we are driving cars which have a slightly higher chance of fire. what they require is an austalian standard helmet which mean stuff all as far as a competition helmet goes. if you can afford it get a motor sport specific helmet as they have fire proof linings.
bell/ simpson /arai/sparco. thay are not cheap . as it is said a $10 helmet for a $10 head. also the better quality they are the lighter which is good for your neck when driving or crashing.

I have had more than my fair share of big crashes in 10 years of open wheel racing in speedway will get you a lot upsidedown time. and i all ways used high Quality helmets.
and are still here to talk about it.
my latest helmet is a bike helmet but i wear a nomex balaclaver under it. to help with the fire issue.
my old helmet is just fine on the out side it just the lining has started to detiorate so it no good for use. it has lasted 9 years so i am happy with the life of it.
