NHRA regulations
If you are planning on running those aluminum slots that are shown in the picture next to your user name, you might have to change wheel studs. They have to extend beyond the wheel by a minimum of whatever the diameter of the stud is. The tracks around here are requiring a suit now (either 1 or 2 piece). I still have a lot of work to do on my Duster to make it legal. I've got a roll bar but the car is probably going to have to have a full cage. My belts are out of date (they can only be within 2 years old). The 2 piece pants/jacket I have is not up to spec if I'm running under 10 secs. I won't be able to use my open faced helmet at that speed either. The faster you go the more regulations there are. I don't have a NHRA competition license yet, but apparently I will need to get one if I run under a 10.00.
