when will I need a roll cage?
 

What's the quickest I can run before I need a roll cage in my car?

Anyone know where I can get a bracket racing rule book?
With the set up I have now, I should be deep in the 13's and could probably tweak it to get 12's
I won't get a chance to find out though until next spring.:(

11.49 IHRA or 11.99 NHRA. I believe these are both for a roll bar though (like a 6 point setup). I am assuming you don't have a convertible.

With traction you should easily be in the 12's.

According to NHRA

11.99- 6pt roll bar (13.99 for convertibles)

9.99- roll cage

You can pick up a rule book at your local track or ask at your local performance shops, they should be able to hook you up with one.

If not try www.nhra.com or www.ihra.com and I think you can order a rule book online.

And at our ihra track, you need a parachute for 150 mph traps:D

Along with what ghost said, you can get an NHRA rule book at Summit (2-3 days shipping..... w/o joining any club/organization....). And to be technical, you only need a 5-point cage (that's hoop, two rear bars and driverside diagonal bar-- and that bar can be a swing out if you want, so can the passenger bar if you have a 6-point) for 11.99 or faster for a hardtop car.
