Here is a "reply to all":
Weight savings (~2lbs): Remove the ISOFIX bar (tube with brackets on ends and 2 wires in between). This is the child seat restraint system required by DCX. Most likely you will have to remove the passenger seat. Unclip the cushion trim cover via the rear J-clip only. This will expose 2 bolt heads on the outside bottom of the seat (above the tracks). Remove these 2 bolts and the ISOFIX bar will fall off into your hands. Assemble in reverse. The trim will be a bit baggy but shouldn't show through to the front side.
VGX is the DCX vehicle code for the vehicle.
DCX specifically did not want any seat adjustments except for fore/aft.
The seat is positioned as low as possible as still meet all the government regulations. I don't know the design of the "lowering kits" but I question if they would meet the strength tests required by law. I'm 6'4" and had difficultly with visibility while in the car. I'm for the lowering kit, but nervous about safety. The buckle is attached to the seat and not directly to the vehicle body (unlike the SR vehicle). Therefore, all the load during an impact travels through the seat structure.
Nope, I don't know Terry Lawson.
One thing that could be done to "widen the lower portion of the seat", if I understand directly, is to bend the cushion bolster wire by sitting on the outboard bolster. There is an 8mm wire welded to the metal cushion frame. The foam and trim are assembled on top of this. You should be able to bend it ~1/2" and not negatively affect the appearance of the seat. Maybe this will help. Good luck bending the inboard side since the tunnel is up against it.
Sitting position:
Everyone has their preference of seat position, especially in this type of vehicle. My preference, being 6'4", was to move the seat forward ~1-2" from full rear and recline the seat more than is possible in full rear. This helped my visibility under the header. Plus, I prefer a reclined posture.
