Seems to be a thread about this already.
A quick summary:
1. Most people think the normal M Sport Suspension is sufficient and passed on the adaptive damper, as the standard suspension rides much better than its equivalent in the F30 generation cars.
2. In terms of stiffness, the standard M suspension is between the "Normal" and "Sport" settings of Adaptive Suspension.
