Hey Bobo, try this link out:

This is where I just bought my helmet last week. Free shipping on any order over $75. The helmet I recommend is the HJC CL-15. It is a quality helmet without the silly price tag. If you get it in a plain color it is $103. There are cheaper helemts on that link, but they are not Snell certified. Any IHRA or NHRA track requires Snell certification in addition to DOT certification.

If you get into the really fast cars, then they require the Snell SA certification (which is for auto racing and is fire retardant and can withstand impacts from roll cages). But you don't need to worry about that kind of helmet until you shave about 3 whole seconds off the SRT-6's quarter time.

Another nice feature of the HJC CL-15 helmet is that the face plate comes off with the press of two buttons and snaps back on. I prefer to take it off completely for racing, then put it back on when I stow it in it's carry bag.

Also, the HJC CL-15 includes a light carry bag with the helmet so that it doesn't get scratched up in transport. It's a good deal.

Lastly, I'll say unless you know for sure what size helmet you need, go to a motorcyle shop and try on a helmet. They'll help you find the right size. Then you'll know which one to order online. Guaranteed the motorcycle shop won't beat that website's price.
