Is this legal?

[dartman]

Got the word back today from Ryck Campbell NHRA, Northeast Division Technical Director


the question was

"I was told I could use an anti-rollbar on the rearend in stock but it had to be a bolt-in unit.
Is it legal to weld in box tubing for mounting the anti-rollbar?"

Answer "No, not in an NHRA Stock Elim. vehicle and it can not be adjustable. I can not speak for other organizations."


add later


Kelly,

From reading ClassRacer, I guess my response was not as clear as I thought. The pan-hard bar can not be adjustable.

sorry for any confusion.

so you can't weld it in and the pan-hard bar can not be adjustable

that should clear things up

so you can't weld it in and can not be adjustable

that should clear things up

And tech guys in other divisions have said the exact opposite. Nothing settled. Call Glendora and get it in writing

"Can't weld it in and can not be adjustable"..........WOW, with this thinking, it sounds like there will be a ton of Stockers making changes since the majority of the cars I have looked at all have adjustable anti-roll bar links.

It needs to be in writing before I make any changes!

Sounds to me like the door is not necessarily closed.
Quite obviously, that one installed by that company, under the Camaro, is very much a departure from a factory unit.
I wouldn't allow it either.
As for adjustable, not allowed.
No kidding. This isn't Super or Pro Stock.
Just do it right the first time, and it doesn't have to be adjustable.
Besides, with our obsession with weight savings, why would a person want extra bracketry dangling around ? !

Ive never herd of this either...and ive been across the country at different NHRA and IHRA races and almost all stockers....coil spring or leaf...have an antiroll bar. An ANTOROLL bar does exactly what the factory SWAYBAR does but more efficiently and its way more solid. I could understand non adjustable links in stock because an adjustable link allows you to add preload. A parnhard bar locates the rear end side to side....an antiroll bar has no side to side properties at all...it controls body roll just like a sway bar. Looks to me like some people just like to argue even if they are wrong

Ive bought, built and broke a tonne of antiroll bars and never has the rear tires hit the quarter panel. So having said that it is in no way even close to being the same as a panhard bar. Some people just buy things and bolt them on their car...these are the people who dont understand the terminology and how things work. They kind of understand because of google but thats about it.

Please...i know its the off season and some poeple are stuck in their house and their choices are listen to their nagging wife or go on classracer.com. Im not looking for an aguement here this is my opinion only and im not fingering anyone out. No internet war please.

As for it being legal I think its ok as long as it bolts into the car. Its better than having a cork screwing tire rubbing disaster. It is a traction device just like a stock swaybar is a traction device as well. Id be more concerned about people having adjustable control arms because I was under the impression that that was not legal. But I have seen alot of coil sprung GM's with upper adjustable control arms. And as for the original post they welded in a brace to bolt the antiroll bar in. The car is sheet metal in this area and you cannot bolt an antiroll bar to sheet metal because the floor will buckle. As for the weld rule I would want it to be a bolt on deal anyways that way you can remove it and service the unit in between races.

Guys, I'm not just trying to argue. I've been in the auto repair business for 50 years, and what I'm calling sway bars have been called that (as well as anti-sway bars) in service manuals since the 1940s and by about every technition I ever worked with for as long as I can remember. Panhard bar is a term I have only heard in the last 10 or 15 years.
You are free to call it what you want. I'm not going to belittle anybody for disagreeing.

[Jason]

Looks like the list of tech guys in "other divisions" who said it was okay to weld in the anti-rollbar is dwindling.

In fact can anyone name any techman who said it was okay? Probably not.

[Chris1529]

need Travis' input.

[monahan]

i ran a ajustable panhard bar 3 or 4 years ago was told by n.h.r.a tech to remove it and put the stock back in also run the stock sway bar never had any luck with that trick stuff gene monahan 1021 stock p.s that was at indy
