BMW aren't very forthcoming with their technical specifications, especially regarding suspension options. My understanding of the F10 set-up is:
1. reduced (softer) spring & damper rates for models without
M sport suspension
2. increased (firmer) rate and shorter springs (to reduce ride height) and increased rate dampers for models with
M Sport suspension
3. reduced (softer) spring rates for VDC option, plus the facility to vary damper rates between the softer standard rate and the M Sport rate
If my understanding is correct then an M Sport model will still have firmer suspension due to higher spring rates than a VDC equipped standard set-up, even though damper rates will be the same if the firmest setting is selected on the VDC.
If anyone can shed some light on this I'd be interested to hear.
