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.

I agree about the usefulness of the subframe bushings, particularly under braking. But it was my impression the instability the other poster mentioned was over highway joints and bumps due to a soft rear spring.

OK, probably turning in for the night.
If nothing else, we've made this forum more lively than it's ever been.

Yep, the forum is dying (just like BMW's driving DNA).
