INTRODUCTION, NHRA DRAGS: STREET LEGAL STYLE PRESENTED BY AAA (5th Paragraph) (Page xiv) (9/18/2018) (9/19/2018) Additionally, requirements 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 (*6.39) 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. Vehicle must pass all highway safety requirements in the state in which the vehicle is registered. Unaltered OEM installed anti-lock brakes, airbag functions, as well as all other OEM safety related systems must be functioning as per manufacturer’s specifications. Note: Tires used may be other than OEM, but they must be DOTapproved. ******Other changes/modifications to items such as but not limited to intake air systems, exhaust systems, computer programming from the factory OEM equipment are considered “alterations.” As such, 2008 and newer vehicles with changes/modifications must meet the Summit Racing Series rules. All drivers must meet the Summit Racing Series helmet and protective-clothing requirements for the e.t. and mph of vehicle.


The three key points here are the OEM anti-lock brakes, removing the factory seats for a lightweight seat....which triggers the airbag light, and DOT tires. Non compliance in any of those areas will put you back to the 11.49 tech limit.

The overlooked word in the rules paragraph is Unaltered. Non factory power adders are also part of this clause but I will defer to someone else for the exact specifics...ie a certified Roush installed unit on the GT.

I'm 99% sure they removed the unaltered part of that rule. The removal of the unaltered stipulation is why they added the factory safety systems.

It appears some of the formatting is missing in your post. Some of that should be struck out
