Adjustable steering force - Was this part of a pack?
 

Hi all,

My manual states "Adjustable steering force" was an option/accessory, however was this option a specific option you could buy or was it part of a pack?

The "Active chassis - Four C" seems related but again could have been a completely separate option or included in a pack.

Anybody got either of these options and could feedback on their effectiveness/usefulness?
