Re: Suspension help
I would try to verify that the chassis is straight and true. The addition of a rollbar shouldn't have caused the problems unless it was installed with chassis not level and well supported if you know what I mean. Or maybe the chassis was tweaked before the rollbar was installed and was corrected and the alignment will bring the handleing back Good luck.

Re: Suspension help
A couple of comments; Was the guy who put the roll cage in a reputable, experienced race car fabricator? If a roll bar is not put in the car correctly it can pre-load the chassis and cause a bunch of problems. The movement to the right upon shut down sounds like front end alignment to me. When you get your car aligned get a 4 wheel alignment. The rear end can be out of alignment and cause launch maladys.
Our cage was put in our car by Mike Pustelney. He also set up the rear. Since Mike does not do front end alignments, he told me to have my alignment guy to try to get these specs: 1) Castor - As much positive castor as you can get so as long as both sides are equal. 2) Camber - Set to zero. 3) Toe - Set toe 1/16" out on the right and 1/16" on the left for a total of 1/8" Mike Pustelney is the man when it comes to chassis building. I think a lot of guys on this forum can attest to Mike P's experience. Good luck.

Re: Suspension help
Was the front and rear end hanging free in the air or was the vehicle weight placed on the the control arms and rear end to simulate it being on the ground?

Re: Suspension help
The tires were touching but he had the suspension fully extended. There was not weight on the tires(the slicks and front tires were with no sign of pressure on them. I have a feeling that is not good? I assume that means the chassis was flexed some what.

Re: Suspension help
Wagons have Boxed Frames, the replacement of floors wouln't make a difference unless the body mounts were were replaced.
I'd contact a chassis builder with a table or chassis beams to check and see if the frame is tweaked? G |

Re: Suspension help
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.
