PBI raceway is by far one of the strictest tracks I've been to. I drove down from GA and they almost wouldn't let me race because my helmet is an HJC (DOT) 'motorcycle' helmet... Sadly I didn't know any better when I bought it. The next time I brought my buddies SA-2010 helmet to tech with and then wore mine, since his was way too big.

One of the nice things with the SLK, I have been yet to be booted for being a convertible in the low 12's.
