So I was going to get another SA helmet when one of the guys I race with informs me that the motorcycle rating is suficient so long as I am not doing wheel to wheel. I may still get one so I can get a HANS but for now I just picked up this

New helmets are good, especially when they have cool graphics.

Where are you located? You can buy helmets online but it is best to go in person to a showroom with a decent selection so you can confirm the size and make/model that will best meet your needs.

Good places here in SoCal include Werks II in Burbank and Sube Sports in Huntington Beach.

I thought most sanctioning orgs require SA rating for any 'track' events not just W2W racing...that one does look nice though

I was under the impression that DE events require SA rated helmets.
SA helmets have two features important for automobile use which M rated helmets don't have.
1) Resistance to damage from contact with roll cage tubes
2) Fire retardant lining.

Our tracks up here don't have any issue for DE. I may do one or two DE a year though. I mostly autocross so it really doesn't matter. I do plan on buying another helmet next year if all goes as planned. I will need to get a Hans

you need to get a HANS? The means you will be RACING next year?

We have a few great rallies up here and I may be starting in rally racing as well as autocross if all goes as planned. However, I can't let this get me off track of getting the GP car built for next year

For you guys that only race once in a while, you can rent HANS devices for weekends for cheap at most tracks or equipment suppliers.
