I don't know what BMW did to the M240 steering, but it is quite a bit different than the steering in my 2016 M235. The M240 is much more dead and more loose. The M235's isn't amazing, but it way better than the M240s.

The M235/240 really need an LSD. It makes a massive difference in handling, acceleration, and chassis dynamics. It fixes many of the ills you noted.

I agree with you, the suspension is the biggest let down in this car. I would MUCH prefer a passive setup than the adaptive. There's just no good setting in adaptive. I totally agree with the pogoing sensation you noted too and it is annoying. I am running Bilstein Dampstronics out back with stock springs and it's helped a bit. I did have Dinan springs in the back with the helper spacer, but they're just too low in the back and make handling a bit wonky. Even with the spacer, the rear looks slammed.

Seeing that you have a 2011 N55 with an PWG, I think you'd be surprised at just how much better than EWG N55 pulls up top. Your N55 has a smaller turbo and runs out of steam around 5800rpm. The EWG N55 makes peak power at around 6400rpms and power does not drop significantly until 6700rpms. It still doesn't have the lungs of the B58 up top, but it basically sits right between the PWG N55 and 1st gen B58. Add a tune and DP to the EWG N55 and it really wakes up in the 3000-6000rpms range. My M235 has Dinan Stage 2 piggyback and HJS Euro catted DP and it's way more than enough for the street (around 380whp/400wtq) for a 3350lb car. A stock M235 makes around 310whp/330wtq. I do REALLY like the B58 though and would not be opposed to owning one.
