714,
Too much body roll, I can't believe it. At what ht. is your car? Do you have it lowered to the ground?
The easiest way to help the situation is to add a rear bar. Go to Speedway Engineering you want the 3/4" straight bar with splined ends.
To connect the bar to the lower arms go the following link:

These coulpers will attach the arms. you need 2.
You need to cut your stock bar off, easist way to remove it. Cut it right at the mounting point and you only need to cut one side. Then you cut off the Stock Swaybar arms where they go from being straight to turning. File, grind a curved contour to match the Coleman couplers and have them welded in-place.
Then you slide the straight swaybar through the mounts and push the couplers on the bar and tighten the set screw. Then bolt up the swaybar arms to the stock links.
Cheap 19mm rear bar.
I will post some pics soon.
