The only thing I'm sure for that moment is that with an horizontal neutral roll axis, the cas is not efficient, you have understeering and a slipping rear at the same time!
Now I have to try lower the front roll center or higher the rear roll center to reach a good balance.
Not that way! Roll centres aren't static when the car is in motion and 99% of the time they should be at least at ground level. For our case RC can never be set underground (most if not all TC use roll centres height of -2mm to -5mm). The front is bad, the rear is worse! For a natural driving feeling the rear roll centre has to be higher than the front. In the end you would make a good change,raising roll centres more than needed is asking for trouble so don't go overboard as you are right in your assumption.
