My suggestion is to call Alf Weibe. He has the A Body suspension wired. I have been using his parts for seven years. His supension launches straight without any lean. I have seen others that have a straight launching car without his suspension. They are rare and require a lot of work. I wanted a perfect launch out of the box. He has really helped me make my car fast and straight.

The NHRA has lately been giving him a hard time. I understand that he has a solution that is acceptable to the NHRA tech department

Here is his email: wiebemetal@shaw.ca

I always thought the correct way to install a roll cage is to have the wheels planted firmly on a level surface but, I am not a pro chassis builder. I agree with Greg, contact a good chassis builder and have him check the frame for straightness. Floor pan replacement on your car should have no effect on the chassis. If you have a unibody it is a different story.

The other day, someone posted that Alf had an updated version that he had an NHRA letter of approval for. The previous version was legal for a while, but NHRA revised their position and forced a change, I think the grace period was over the first of this month, or will be over as of the first of next month.

I've heard conflicting reports, did they tell you specifically what was actually illegal about it?

By the way, I looked several times over the last couple of days, and cannot find the post about Alf's new NHRA approved stuff. It had a picture of an NHRA approval letter. It was hereon the boards for a while, but now it is either gone or I just can't find it.

Also it is a result of not having sway control as stated by Dragsinger. The leaning is normal. I am assuming that your car leans over when turning and when you get it straight and burp the throttle, the front end will come back to normal ride height. If it stays leaning, there is a problem somewhere in the front suspension mechanicals.

I do have 90-10's on the front and 70-30's rear. Yes once straightening out the car comes back to level. Thanks for the help.

I just stumble upon this thread and i have a question about front suspension. we have a 68 chevelle 396 325 car and when we are stalling on the starting line the front wants to raise how can that be cured?? The more the stall the higher the front fender goes on the hit it does great we would just like to have the front settled as we are staging

A rear "anti-roll bar" will cure the leaning and make the car overall more stable. It is very likely that a properly installed and properly adjusted anti-roll bar will allow removing the air bags.

Please correct me if I am mistaken, I think a bolt on kit is legal.

Thanks for the help Dragsinger. A rear sway bar might control the handling since the roll bar was added. Down track it wanders a little and sometimes moves left when braking in the shut down area. I am assuming that the roll bar installation lessens "normal" body flex (it's welded to the frame),

If you're getting it realigned you had better find out what it was setup to beforehand, at least if you plan to take it to a normal alignment shop, because they'll want to set it to stock specs, and it will likely make your problem worse.
