Check your sanctioning bodies rule book before making decision on a racing helmet. There are differences between most racing sanctioning bodies rules, so don’t show up at the race track with the wrong helmet! NASCAR rules are different than what your local dirt track or paved oval track may require. IMSA, Grand Am Racing, Trans-Am Racing, American LeMans Series Racing, SCCA Road Racing and Autocross, NASA Racing, SCORE and BITD OFF Road Racing all have differences in their safety requirements. Most US racing sanctioning bodies will require SNELL SA 2010, SA2015, FIA or SFI 24.1 rated helmets; Some sanctioning bodies may allow one or the other. The UPR Racing Supply staff will help you make a selection for your racing helmet, but it’s up to you to know the rule book for the type racing you will be participating in.
