Should I buy an SA rated or M-rated helmet?
If you are planning on attending an event with a group that requires an SA helmet, you might want to plan on buying an SA helmet. Some of these groups require SA helmets and will not allow you to pass tech with an M-helmet.
My Helmet is DOT approved. Isn't that good enough for autocross?
Your DOT sticker means nothing to CSCC.
We only allow helmets with the holographic SA, M, K, SFI or BSI stickers.
You cannot and will not pass tech with a DOT-only helmet.
- Allowed helmets:
ECE: 22.05 (Reg 22 Ammendment 05)
SA: SA2010 or newer.
K: K2005 or newer.
M: M2005 or newer.

CMR: 2007 newer.
