Everything is completely free on both sides - arms, uprights, camber links at both ball studs, dog bones. I just dont get it. Any ideas???

Update: did some more work trying to fix issue. Ive taken it down to only the rear arms and sway bars installed. Double checked the arms move freely on pins on and off the car. I have tried 2 different roll bars and flipped each one of them over. I am still getting the left side lifting around 6mm and the right around 12mm. At one point I got it to around 7mm on left and 9mm on right but it was late and I kept working at it to get it perfect but never could get back to that close of a value.When I adjust the heights of the arm holders it seems to have little or no effect. I did notice I have a little lift on the back right corner. With the chassis sitting flat on setup board I can rock it slightly. I loosened every screw on the bottom and top but the lift in that corner would not go away. Not sure if this would be enough to cause the roll bar issue but I did press the chassis down so it was perfectly flat on all 4 corners and tested the roll bar with same results as above. What I do know is that regardless of swapping parts in various combinations side to side and from car to car the problem varied only by 4mm or so and always with the left side lifting the right side almost immediately and the right side lifting the left side at a much higher value.
