You're setup had a fraction of the suspension travel of the one's we're talking about. Nor the same spring rates, nor the same dampening. So again, you have no basis for making this statement beyond VERY broad generalizations.

I said nothing of instability in the rear end. I said the car was underdamped. A common problem when running a stiff spring without a correspondingly stiffer shock. This is a problem typically solved by stiffening up the dampers.

The bit of rear-end play in all E90 cars is largely (albeit not completely) addressed by subframe bushings, which I installed last week. Not that wifey cared all that much anyway. But they're really a must on all of these cars for anyone caring about this sort of thing.
