helmets
It is very important to get a proper fitting helmet. You should take careful measurements to get an exact fit. I would recomend Simpson or Bell. I have used them both in open and closed face. In autocross, racing a street car I have used an open face and stayed confortable. If you have any plans to race and open wheel or any other class in S.C.C.C.A. road racing then use a closed face for added protection. I have been using Simpson closed faced for many years and am very happy. If you plan on racing a lot, then I recomend you get a kevlar or carbon fiber. The weight difference is amazing.
Remember, that is your head you are protecting, it is not worth trying to save a few bucks on a cheap helmet.
Just my 2cents worth
