So here's an interesting question. In looking through the parts catalogs for the 2014 GC, there are a number of suspension options/codes and associated parts:
SDA - "Normal Duty" which seems to be the norm.
SDM - "Export Tuned" which I assume is for export versions
SDX - This is the SRT suspension
SDE - "Sport" suspension.
This last one is odd. Apparently there are part numbers and parts for Quadra-Lift equipped and non-QL suspensions with the SDE code -- yet, I see no way to actually configure a vehicle which ends up with this particular suspension (and what "sport" actually means).
Anyone have any ideas? Milous perhaps?
