If your car is making 500hp, with slicks here are some of the basic things you will need before you go (not a complete list).
Helmet
Pants (no shorts)
closed toe shoes
Drive shaft loop
3 inch wheel studs
aftermarket axles
battery hold down
If the battery is in the trunk, a cut off switch is mandatory.
Double springs on the carb
Neutral safety switch
Locking dip stick
If your car goes under 11.5 (which if it really is making 500hp, it should) you also need:
Fire resistent SFI approved jacket
Rollbar
This is just a few of the things that you will need to before you go (NOT all). Get an NHRA rule book and take a look for a complete list.....isn't racing fun!?!?
