NHRA Rule for Roll Bar????
Does anyone have a 2005 NHRA rulebook and can answer a question for me? I heard that this year the requirement for a roll bar has been changed from 11.99 and faster to 11.5 and faster. Anyone know this to be true for a fact?

nope. aint heard nothing about it yet.........but, ill probably want one as soon as i break 12's, cuz, i know ill wanna go faster....
i figured theyd leave it at 11.99's, cuz .5 is a lot of time in drag racing.......that can be a HUGE difference in mph......

RE: NHRA Rule for Roll Bar????
LOL..... yeah I have become pretty wise in my old age. I have pretty good tinting but it is still hard to hide a big roll bar. The other thing for me is that my interior (other than the additional gauges) is very stock with leather interior, AC, stock Mach stereo, power drivers seat, etc. I want to keep it that way. It is very comfortable for street driving. A comfortable street car that runs 11.6 - 11.8's; gotta love it. I don't drive it on the street that often but when I do I desire comfort while flying under the radar.

RE: NHRA Rule for Roll Bar????
Do I need a helmet, and if so, what kind?
A helmet is required for the driver of any car or truck running 13.99 seconds or quicker in the quarter mile, and for the rider of any motorcycle. Most drivers can use a helmet meeting SNELL M85, M90, M95, SA85, SA90, SA95 or K98 specifications. Professional category and some alcohol burning vehicles require an SA rated helmet. It is important to note that the helmet rating must be designated on a tag INSIDE the helmet, or sewn to one of the helmet straps. The designation stenciled on the exterior of the helmet is insufficient for NHRA technical inspection. Also, some tracks require a helmet on ALL drivers, so check in advance.
When do I need a roll bar or roll cage, and what should it look like?
A roll bar is required in any convertible running 13.99 seconds or quicker in the quarter mile, and in other cars beginning at 11.99. 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, and must conform to the following diagram:
If the floor and/or firewall has been modified, then a full roll cage is required beginning at a 10.99 e.t. A full roll cage is required in any vehicle running 9.99 seconds or quicker, and any vehicle running 135 mph or faster (regardless of e.t.). The roll cage must be constructed of minimum 1 5/8 o.d.x .118 mild steel tubing, or 1 5/8 x .083 chrome moly tubing, and must conform to the following diagram:
The roll cage of any vehicle running 9.99 or quicker, or 135 mph or faster, must also be certified by NHRA every 3 years, and have a serialized sticker affixed prior to participation.
