Bilstein PSS9 Dampening

I recently installed PSS9’s on my 996 C2 and while experimenting with the rear dampening settings it seems that even with the most firm setting (no.1) it is not enough. When you push down in the rear the car comes up higher than the resting height and then down again. Unlike the front, push down and it comes to the resting position. On the softer settings (7,8,9) the rear is significantly under-damped. At night you can notice the headlights bobbing up and down.

I am looking for some feedback before sending the shocks back to Bilstein. What settings are people using?

Thank you.

On my daily driver C4 6sp coupe w/PSS9's I'm currently running settings of 5/4 for the front/rear respectively, but I still detect a slight amount of bounce at times and will probably stiffen them one more step.

PS - I found that the car needed to have one step difference between the front/rear to avoid a pattern of sympathetic bouncing behavior; and it's worse with softer settings.
