Test drove a E46 330CI and a E90 325i and it makes me appreciate the steering in the 135i even more, definitely much better than the older models, although the cars were much older, so not sure how much was wear and tear on the steering components.
Apologies. Responded too quickly thinking this thread was was about the sloppy shifts.

One thing that addressed the floating sensation coming from the rear of my 135i is the replacement of the stock subframe bushings. These are so soft that you can squeeze them in you hands. Try this when you are ever under your car - the subframe can be moved with a light force from a large screwdriver or crowbar.

Easy and cheapest way to address this is with buhings inserts that will fill the voids in your stock bushings.

Best way is replacement with M3 bushings, but the rear subframe has to be loosened, and driver side brake lines detached.

The stock front control arms can be replaced with the M3 ones as well, which have sturdier bushings, and provide about -0.7* of negative camber. Both of these features help with turn in and steering preciseness.

Did this to my 135i which I take to track, and it helped a lot. Big positive impact to car behavior on the street as well...
