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.
