I tested a F10 530d with all the electronic damping stuff + active steering + 331 19 "alloys. Nice smooth ride and in sport it still feels like a Citroen C6 compared to my E90 M3 also equipped with EDC in soft mode
I love and I 'm used to a firm ride(with a 120d/330i/335i equipped with M Technik and 17"/18"RFT's) for the past 5 years or so, hence M3 is a bumpy car....
I know a 5 series is more about comfort than sports, but I opted for the somewhat firmer and 1 cm lowered (code 704) OEM M Technik suspension + 19" 331s and my dealer told me today M Technik is not compatible with the electronic damping stuff so I stick with M Technik.
