I do not have a roll bar. When all is said and done, the car is 98% street, 2% track, so I'll probably never put a roll bar or cage in it. I enjoy the comforts of having a 600+ rwhp cruiser.
I mostly go on test n tune nights where they aren't strict with what times you run, but back in 06' I did receive the boot for running too fast. Kind of the reason why I haven't been back yet, so they forget me, haha.
When I go back with the KB at 23psi, I hope I click off a real good pass because I imagine I'll get kicked out pretty quick.
