Suspension help
 
I have a 69 Chevelle wagon that is a "natural" K car. It is a stocker and the suspension is the same set up from when W A Lee owned it as far as I know. When making any turn the body leans over greatly. The rear had one air bag on the right when I bought it and the front end lifted the left front off the track and the right stayed on the ground. I installed an air bag to the left and ran about 15 lbs on the left and about 30 on the right and it picked both front tires about 8 inches on the launch. I would like to update the suspension front and rear but I am curious about the way the car leans(scared the heck out of the local fire dept at one race on the turn off!). I have been told that the lower ball joints must have been lenghtened for the car to lean like that. Is that correct? Also notice that when the front tires are off the ground they appear to be straight not cambered in or out like so many cars I have seen. Is this set up good or bad.
Thanks to any and all help you gentlemen can give me. Not looking to set any records just want to be competitive..........lot's of luck!!

Off the ground and straight is a good thing assuming they are straight when their when on the ground. Sounds like a good setup.

I have a 69 Kingswood O/SA and it does the same. The rear has a spool in it and when u turn it makes it lean. Both wheels turn the same...no slipage.:rolleyes:

Most of the bracket cars that I have seen with coil springs on the rear, lean when they turn. Most have spools also,. guess that's normal. Most leave the line flat also. Most with air bags.

Re: Suspension help
 
the leaning you describe is a basic characteristic for that suspension style. [basically, you have the car sitting on four coil springs with nothing to control "body roll"]

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.

My brother and I have basically the same car as you (Ours is a 71 Chevelle wagon, natural K/SA). The leaning is the result of using a 90-10 shock on the front. 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 have an A body. A C/SA 1970 Chevelle. If you are using the stock suspension, you will have the A body lean.

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

The tires are straight when on the ground. I am going to get it re-aligned as since the roll bar was installed it "wanders" a little down track.
