Some rule interpretation questions.
Hello, have a couple questions regard stocker interior and exteriors. I know you are not allowed to add a wing or spoiler that did not come on the car, but prior to my thoughts of running stk with this car I took the spoiler off the car that was there. So are you aloud to remove a spoiler?
Also if you have a roll bar in the car, but it is not a 100% must that the back seat needs to be removed for fittment of bars , can you get by with it from tech and fellow racers? Especially if the car is not fast enough to require a roll bar? I am doing a sort of multi purpose car, and have my own reasons for wanting the roll bar in. Thanks for any help. |

2, If you are asking if you HAVE to remove the back seat with a roll bar, the answer is no. You can put your back brace(s) over it, under it, or through it.

Re: Some rule interpretation questions.
On the spoiler issue, if the body you are considering had a spoiler option, you can run it with or without a spoiler. An example would be the '94 T/A I once owned. If I wanted to race it as a T/A, it would have to have the rear T/A spoiler. If I wanted to race it as a Formula I would need the Formula spoiler. If I wanted no spoiler I would need an engine that was not Formula or T/A specific. That help?
On the roll bar, NHRA looks at it this way. You may not need a roll bar due to the car being in a slower class. BUT, if you install a roll bar, it has to be up to spec; just as if your class REQUIRED a roll bar. NHRA does not allow cutting corners on such issues. So it's either all or none in their eyes. The same applies to seat belts, even on a bracket car. You may be allowed to run factory seat belts and NHRA wont care. But as soon as you put aftermarket racing belts in (even if only a lap belt), you are subject to re-certification or replacement every two years.

Re: Some rule interpretation questions.
On the question of back seat, in or out. If you remove the rear seat, be it a
stocker, SS or just bracket car the rear seat area must be "finished off" with a firewall and carpet. Maybe on a stocker if the battery is in the stock location and you are using a stock tank you could get by with just fiberboard and carpet over the area where the seat had been. But add a battery in the trunk and a fuel cell and then you are back to a firewall and carpet.

Re: Some rule interpretation questions.
Thanks guys. I am familiar with all the standard nhra rules for batteries, fuel cells, firewalls, roll bars etc. I just wanted to make sure that if I have a roll bar in a mid 12 second car with no back seat, racers and or tech would not have anything to say about it. I am not particularly new to sportsman racing, just finally giving some serious thought to running stock next year. I work in the engine business, and have also have alot of experience in custom interior, and have some creative ideas I would like to try.

Re: Some rule interpretation questions.
You can have a roll bar or cage in a 20 second car. Just has to be per the specs. Looks like your on your way. Good luck.
