the NEW roll bar exempt only applies to unaltered hardtop cars 2008 and newer slower than 9.99 135mph
so if you run 10.0 or under 135 you are good ,
but once over 135 or 9.99 ... roll cage time
and even though rule changes state you dont need a roll bar , the initial release of the change doesnt say anything about the rest of the car or driver . if its just the roll bar the rest of the required items for your et speed will be needed
and rule also states "UNALTERED" ..
NHRA DRAGS: STREET LEGAL STYLE PRESENTED BY AAA (Page xiv) (5th paragraph)
Additionally rRequirements and specifications for Street Legal are the same as those for the Summit Racing Series with the following exception: Unaltered 2008 OEM model year and newer production cars running slower than 9.99 and 135 mph do not have to meet the requirements and specifications for the Summit Racing Series except for the following: Convertibles and T-tops must meet Summit Racing Series Roll Bar and Roll Cage requirements, All drivers must meet the Summit Racing Series Helmet and Protective Clothing requirements.”
100% UNALTERED cars only qualify for this ,drag radials,slicks,cold air intakes etc. and you need a bar. This will not effect the faster and smarter drivers here so buy a bar if you plan to go fast.

from a post on SVT forum when they asked NHRA about "unaltered "
* The rule applies to any 2008 or newer unmodified (bone stock) hardtop;

Bout time. I disagree though. "Unaltered" has not been defined yet. I take it as cars that don't have body kits to make them lighter. The rule would make no sense since there are no 2008 cars that run 9.99 bone stock. So you can take a 08 poopstang hard top, and as long as the body structure is not 'altered', you can put slicks and a nasty motor in her and run 10s with no cage without getting booted. Otherwise, the rule would be geared to cars made in 2014 where it would basically give the automakers permission to make faster cars. The zr1 does 10.30s with drag radials only. that's the way i took it after reading for 5 minutes. i could be wrong though. i will read it some more. cool change though especially for my Z.yup as Pauly pointed out the key word is "Unaltered". Most cars going that quick will not be stock and will technically require a bar.
