according to this they didn't list Snell M2000/2005 which is what the helmet is that I was looking at.
I'm concerned only because a lot of the race's Moroso has if I want to compete actually check the cars for the most part. And I can get away with some but I just don't want to get to the track and have them say I can't race because of something. Which happened at nopi to an Evo guy I was parked next to. He had to spend most of the morning looking for a racing suit before they'd let him run.
And me I have to barrow Jenny's Bike helmet so I can pass tech and then switch to my old Black DOT helmet after I pass tech. And personally it's just time to get my own.
