my friends bought some helmet but they don't allow they use those because they said those are motocycle helmet, we need something called DT2(I don't rememer) or whatever helmet to use on track. what is that???? DOT?

 

Most places require Snell rated helmets for track use. The specific requirements depend on the group, but SA2000 is the most stringent standard you'll find. Buy a Snell SA2000 rated helmet, and you'll be fine. Full face is safer, in the off chance you try to break your steering wheel with your face.

 

May I suggest that you read this thread from the up and coming Fall Colors Tour forum:

I believe that the post as well as the links will be helpful to you. As the former National Sales Manager for Bell Helmets PM me if you have any specific questions.

 

is Snell Approved means SA or M 2000 rated?

 

You want SA rating, not M

 

so what are most new motorcycle helmets rated?

 

SA rated helmets are fire-proof and are subjected to different impact tests designed to resemble the sorts of repetitve, directed impacts you would see in a race car (e.g. against the rollbar) vs the single massive impact a motorcycle helmet is usually subjected to.

The SA rating is for cars
The M rating is for motorcycles

 

usually HPDE's only require M95 or whatever a normal motorcycle helmet is...... yes it is safer to get a SA2000, but you can usually be ok with a motorcycle helmet.

I took my motorcycle helmet with me to get my comp license....derp... i had to borrow a car helmet until i could buy one.

 

Ironically enough, in these days of more cost effective production to maximize profits, many SA and M helmets are the same; except for the fire safety lining. In other words, many M helmets are actually produced to a standard that allows them to pass the SA impact testing.

 

Matt,

Thanks for the link and info. I ordered one today. It will be fine for me for auto-x.
