NHRA Roll CAGE Rule
I was just wondering if anyone knows what the ET or speed cut off is until you need to put a roll cage in your car? I heard they lowered it to 10.99 this year is that true?

Re: NHRA Roll CAGE Rule
Right from NHRA's site.
A roll bar is required in any convertible running 13.49 seconds or quicker in the quarter mile, and in other cars beginning at 11.49. The roll bar is accepted in vehicles running as quick as 10.00 second e.t., provided the stock firewall and floorboard is intact, other than for installation of wheel tubs. The rollbar must be constructed of minimum 1 ¾ inch o.d. x .118 inch wall mild steel tubing, or 1 ¾ x .083 chrome moly tubing.
