Just chipping in to share my option.
I fitted Bilstein PSS10 B16 KOMFORT to my F30 (48-229012). These have a longer spring than the normal B16 PSS10. Lowering is in the -10-30mm range, not the -30-50mm range for the normal version. I didn't want to go that low.
I fitted them because I don't rate the standard M Sport suspension ( I've had both Adaptive and passive, both suck!!!). Verdict, wow what a transformation, the car now rides like an M3/M4, no jokes it really does stick to the road. It is also far less crashy when going over potholes, etc. An amazing transformation
