From what I read at the SMF website, the Motorcycle rating is higher than the SA one. So why wouldn't a Motorcycle helmet be ok for track duty?
Or I guess my question is, what does SCCA mandate?

I believe the M ratings do not have any flame retarding rating where the SA ones do. You don't tend to get trapped in your motorcycle after a wreck. I'm sure someone will correct me if I'm wrong.Quote:

I read on some site I visited via Google that just about any helmet can meet DOT requirements.
As a novice driver, I don't think I have to worry too much, unless another novice causes me to wreck/wrecks in to me.
I was also curious...since I don't wear a helmet usually, if you and the instructor are both wearing helmets, can you still hear each other while you're driving to be instructed??
I'm really excited about this event...I am learning a lot about a lot of things....like helmets and trendy shoes ((heh)).
So what's required? The M rating or the SA rating?? I was with the impression that the paperwork said M2000 or better...Quote:

Some track day organizations are starting to require SA. Most if not all autocross orgs are happy with M. M is more readily available and typically cheaper, all else equal.
Makes sense above flame resistance (retardance, don't boycott me). However, the more hardcore racing (<10 sec 1/4 mile maybe) require a nomex backlava (not that honey filled sweet snack).
Thinking back now, I believe reading somewhere about the differences. Motorcycle crashes usually have higher G spikes whereas automobile normally have lower sustained forces/multiple impacts (think hitting the rollbar/rollcage). I'll see if I can find the article.

There is also the big debate on if you should wear a full face helmet in a car with airbags... Apparently, nasty things can happen to your neck if the airbag hits the right spot on the chin of the helmet.Quote:

I understand the point though. Without testing data, it's speculation for the level of physical debate. The way I see it, it can't be worse than being 3 inches away from the wheel.

I just recently bought a new G-Force open face SA2000 helmet locally from Robert Vick at Vick Motorsports. He's located just off off SE Loop 820 just before the I-20 split. He was closing out the old helmets and I picked this one up for $105. I think he had the newer SA2005 versions for around $169. Didn't seem like a bad price for an SA rated helmet. Although now I've got a $20 head riding around in a $105 helmet :D
I got the helmet - snell m2000. No nastiness/odors, looks brand new with the exception of a few scratches. $50.00 - it is full face with a visor. Will definitely take the visor off - I don't like helmets.
Depends on what you want to do. For autocrossing all they require is M95 or higher. Club racing requires an SA rating, iirc.Quote:

The SCCA toyed with the idea of banning full face helmets in airbag-equipped cars following the incident, but decided against it.Quote:

I just put a note on my instrument cluster not to look up when I roll over. ;)Quote:

I think you mean balaclava, not backlava.Quote:
