I finally got money for a helmet! What rating does commerce require?

I'm definately doing 13s. Last year I just had an exhaust and was doing 14.1. Now I've added stage 1, spiking 18psi, 60mm TB, and some other small things.

then you don't need to wear a helmet, not that it's a bad idea, but it's not required.

Helmet is required when running 13.99 or faster...Snell 90,95,2000 will work SFI 31.1,31.2,41.1,or 41.2 will also work..
