I have not read every thread...I retro fitted ZCP struts to my E90 back in ~2012.
I lived in Germany at the time and purchased an E90 ZCP strut set from the forum.
There was a German fellow who worked on all of our M-Flight cars, and he is the one that installed mine.
At that time, I installed the Dinan Stage III suspension as well. So different springs, top hats, camber plates, bump stops, front sway bar, etc.
Also, BPM installed the correct software for the ZCP pack, along w/ Euro MDM, and multiple other coding/tuning options.
The car is been perfect ever since and I love the way it handles and feels.
As a caveat, since the ZCP retro-fit, I have done solid subframe bushes, upgraded diff bushes, and the upper control arm bearing/bush.
Anyways, I love the fact that I went w/ the ZCP retrofit. I've run 55 laps at the Ring and ~20 of those w/ the ZCP retrofit...definitely improved my laps after install.
