All, As some of you know I have been talking about getting into autox and track racing for a while now. Now that I have income, it is perfectly feasable that I will be able to fix the differential on the S14 and be able to pay for track/seat time. My car will meet the vehicle code standards, but i do not have a racing helmet. Whats the deal with helmets? Dont most sanctioning bodies require something that is no older than 5 years (saftey certification)? What should I look for as far as form/funciton? Do most of you who race order your helmets online or buy em at a performance shop? How should I make sure i get the right size for my head? Bla, so many questions - thanks in advance.
