Thanks for that pdf of the instructions! That saves me copying them and posting.
Indeed, Suplex insist that the whole kit is fitted together, they even prohibit using the kit with lowering pins as this takes the dampers outside their effective working range.
Apparently, the Springs are progressive, so that lower means stiffer.
They state that using these kits on a Trophy, and setting up in the above manner will set the suspension height in the range for Trophy spec.
I can only think that the difference in stiffness between the Trophy hydragas and the Suplex setups will be very noticeable.ie much softer/compliant. This will mean a much more comfortable ride but it will be totally subjective as to how the Trophy owner reacts to this.
