SA race helmets

[ArisESQ]

recently the idea of actually racing my car on a track has become very attractive to me. i did some research, and decided that i would like to pursue racing for fun.

does anybody know of any good brands of SA approved helmets, and where i could get them. the only information ive really found about what makes one helmet better than another is just weight... so any other info would be great.

thanks!
