The rules are 7.49 and faster require a rollbar, what I wanted to know was how strictly they enforce that rule. I ran 7.45 my last time out at NB and I've gone as fast as 7.24 up in Jersey, should be a lil faster than that this year. Worst case is I get booted from MotorMile and then I'll just run at NB until I get a rollbar.
