Been looking for these two posts on and off for the longest time, finally found them again. May find some of the stuff useful regarding BGTV8’s rationale on trying not to lower the car too much.

The Z does not have a linear camber curve in the rear. How can I explain this. This is just an example. Say you have your camber set at -1. Squat the rear inch, camber goes to -2. Squat 2 inches, camber goes to -3. In the Z, squat 1 inch, camber is -2. Squat 2 inches, camber is now -3.5. Also, the lower the rear. The more non linear the camber curve becomes. Lower the Z by 1 inch. Camber at -1. Squat 1 inch, camber is now -2.25. Squat 2 inches, camber now at -3.75. I don't know what the exact numbers are. But that's the way is was explained to me from AM Perf.

I have been told that the rear camber issue can be fixed but it is expensive. Requires totally modifying the rear subframe and pickup points. I never got into the details of it but I may later on.

That's what i was told too. That to correct it, Some of the pivot points have to be move. It's not cheap and involving lots of engineering.
