Auto Racing Helmet Ratings
Auto racing helmets are rated by the Snell Foundation as SA, M, or K rated...
Snell SA Rated Helmets:

Snell "SA" (Sports Application) rated professional helmets are designed for auto racing and provide extreme impact resistance and higher fire protection.
Snell M Rated Helmets:
Snell "M" (Motorcycle) rated helmets are designed for motorcycling and other motorsports. They offer less protection than SA rated helmets.
Snell K Rated Helmets:
Snell "K" (Karting) rated helmets are designed for Karting applications. They are subjected to the same test standards as SA helmets except they do not require a fire retardant interior.
The differences between SA and M Rated Helmets:
- SA standard requires flammability test while the M standard does not.
- SA standard has rollbar impact test while M standard does not.
- SA standard allows narrower visual field than M standard (Some SA helmets aren't street legal).

Does my helmet meet the necessary Snell requirements?                                                          Always check your club and or racing sanctioning body rule book to determine what helmet specifications they require. Most seem to allow you to use the current Snell specification, as well as the previous Snell specification. So, in that case, for the 2019 season, you could use Snell SA2010 or Snell SA2015 rated helmets. Snell M2005/SA2005 helmets no longer meet current requirements. The bottom line is... always read your rulebook carefully.
Also, if you are considering the purchase of a Snell "M" rated helmet, be sure that your club will allow them. For instance SCCA Solo does allow Snell "M" helmets, although some organizations require "SA" rating. We recommend using the "SA" helmets because they will be legal for any type automotive activity you participate in.
What is the current Snell rating?
New ratings typically come out every 5 years. As of October 2015, the current Snell rating is SA2015. We currently carry Snell SA2015 helmets. Snell M2010 and Snell SA2010 rated helmets are no longer available.
