New NHRA rules?? roll cage

[AngelSpeedFreak]

Just wondering exactly what this might mean for me? Does this mean that I don't need a roll cage?

My main question would be Does "unaltered" refer to suspension or mean totally stock, I.E. stock power train?

NHRA DRAGS: STREET LEGAL STYLE PRESENTED BY AAA (Page xiv) (5th paragraph)
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 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.

By "unaltered" I think they mean that if you have a 2010 Camaro with a "Factory" block, then you are good. But if you have a 2010 Camaro with a 454 and a 9" rear end, then you probably are no longer within those guidelines. Now that "Factory" block could be built. I think that is what they are getting at.

Or do they mean cars like a zr1, viper, etc that run faster than that bone stock and any mods at all, means you still need a cage.

135mph still screws me over but if I could get the wife's car to go 10s without a cage I would be happy.

As you know, my local track (Albuquerque) just said they heard from the NHRA and if a camaro has a supercharged that it did not come with stock then it will still need a roll cage. Now if it came with one (lets say a ZL575) then it's okay. That makes no sense to me at all as they are the same car?

oh well, I planned on putting a cage in this winter so I will just continue to do so.

I doubt this. Unaltered typically is referring to the firewall and floor.

Can anyone shed light on this, thats going to be pretty important exactly what they mean by unaltered. does that mean factory block and drivetrain, or does it mean bonestock? Any idea`s on how to find out? I`m in the same boat, do not want a cage and can only go to track rentals where they look the other way.

That sucks

[Unreal]

ZL575s wouldn't count. Those are just modded cars from SLP. Would be no different than anyone else bolting a maggie on. ZL1s would count but the odds of them running faster than 11.5 bone stock is pretty much non-existent.

[white ZL1]

I still don't think you guys are any closer to the truth. I'm pretty sure that the rules above are referring to the stock car classes.
NHRA stock car

The amendment above is referring to Street Legal.
