We currently have an early E60 with runflats and the sports suspension, it doesn't get any more extreme than that! I don't think you'd last 5 minutes in it leosayer

I am really looking forward to a more comforting ride but don't wish to compromise "drive-ability". Ultimately it's down to those test drives but I think it's interesting that most examples of the 30d I have seen, well at least half, have the dynamic pack ticked.
Kind regards
JJ
