The M sport suspension is new to the US for 2013 although it has been available longer in most other markets including the UK. That's why our UK friends know all about it and most US owners don't know what the hell it means.
The setup is slightly lower so it uses different springs. The visualizer actually shows this.
If you want the benefit of adaptive dampers along with stiffer springs you would have to order DDC and change out the springs, which some contributors to this forum have done.
