Like Watsey in that thread, I have Whiteline KDT917 subframe bushes on my M235i. Removes that horrible loose feeling at the rear of the car with side-to-side hopping and also improves steering feel. I tried the Powerflex inserts, but they were not good enough for me, but I guess a good improvement.

Previously had subframe and diff bushes fitted on my E92 335i. The diff bushes, KDT919 added a significant amount of NVH which I didn't like.

My '17 M240 darts or travels in ruts or other road anomolies, I changed all of the front control arms in effort to fix it but it made 0 difference. Do you think its the subframe bushings? or rear control arms? I have the x drive so I have no wheel hop, just drifting or darting.

I can't say for sure if subframe bushes would solve your issue. All i would say is that the standard bushes allow quite a bit of flex in the rear subframe, i.e. front to back, side to side and up and down, so can be affected by ruts in road.

I'll probably replace all of the rear bushings with whiteline bushing or just go for the megan arm replacements to have heim joints. The Megan route may be too harsh for a daily driver though.

I have replaced all my rear arms with megan arms and the front bushings are now all spherical joints, not too harsh for the road at all.
