Yesterday I added ACS Springs to my 2012 550i M-sport. My car does NOT have ARS.

So far, the springs are awesome! The change comes from both lowering the car a modest amount and the stiffer springs.

Body roll, dive on braking, squat on acceleration and steering responsiveness are all changed for the better. The car feels much more like a SPORT sedan now and closer to my 2009 E60 550i M-Sport. The F10 is bigger and more luxurious so there will always be some differences. DHP works fine and so far no adverse issues.

I will report back when I have some miles on the springs.
