Couldn't take the beat-down ride any longer - not tolerable where I live.
Drove a 50i with M Sport/M Performance w/ adaptive and there is a giant difference in road hazard (pot holes/frost heave) comfort. The 'sport' on/off provided a definite change - one that was not present with EDC on/off in the ///M.
To my butt-meter, the 50i M/M with adaptive was still more comfortable over bumps in 'sport' than the ///M is with EDC off. YMMV.
A little less high strung, but sounded great and moved along nicely with 440'ish hp. I don't care if I give up a few tenths to 60mph.. this is my daily. Love the 8 speed trans.
Should be here in a few weeks.. more to follow.
