No lice, i'm not fond of that kind of pets....
SA05: i think it's not SA05 rated after a quick google search. All i know it's usable if you track your Elise because it's Snell 2005 compliant and also indeed you can use it on a motorcycle, i bought the helmet in a motorcycle shop.
Post a pic of the Snell rating sticker. That will show whether it is SA rated (auto) or M rated (motorcycle). You bought it in a motorcycle shop, so that seems a likely indicator it is motorcycle rated and not auto rated. If it is an M rating, then it isn't legal at many (most?) track events.
Also, you may want to reduce the size of your pictures before posting them.
