Helmet recomendations

Check out www.helmetcity.com. They advertise in Natl Dragster.

Another source is www.saferacer.com where I got my Bell a bit cheaper because of shipping policy vs. helmetcity's.
I test fitted the Bell at the SEMA show and agree that different head shapes may work better with different helmet brands. Vents don't help us much as we (most of us) aren't on motorcycles. High priced helmets are often because more advanced materials are used to save weight. We don't use them for very long so that is les important than for motorcycle riders. OTOH if you go to the Snell website, you will see that the SA series have several advantages for us vs. the M series.

Always choose a FR (fire retardant inner liner), step away from M helmets, they are not built for Car Racing. The Nylon inner liner burn and melts in your face...not good.
A Full face helmet is probably the best buy, the open face helmets are on there way out of the rule books.

A good helmet that fits well is always worth the money. I would not choose the S, M, L, XL sisze helmets, If you instead choose the hand built helmets in 1/2" inch sizes will you propapbly get at helmet you like.
Besides that is the choice between big or narrow eye opening, Drivers in S/SS and other brake classes do prefer the big opening. AND finally, alway shut the shield when racing.

And, the SNELL 2010 standard will be available in october.
