Hi, I think you really need to put some old clothes on, grab a torch and slide under the car and look around. It is not hard to figure out once you see it all. The centre of the diff cannot move - it is fixed. The springs have no impact on this.
All 3 springs act to control the angle of the axles relative to the ground. They are all providing a force to keep the axles horizontal. If any of them are removed, there will be a drop in suspension height.
The big vertical springs are pushing the axles down away from the body - remove that force, and the body will come down relative to the axle, and in doing so, the camber will change.
The compensatng spring is mounted horizontally above the pivot point - it is trying to push the ends of the spring away from each other. As an exercise, think of this spring as a rod of a fixed length. With the axles horizontal (normal car height), the 'rod' will be a certain length. Now if you make that rod longer, the axles must move down so the rod can fit. This will raise the car. And the opposite is true - make the rod shorter, and the car will drop. The compensating spring is just a rod that can have a variable length. A stronger or longer spring will act like a longer rod in normal circumstances (ride height increases), whilst a weaker or shorter spring will act like a shorter rod (ride height decreases). However, if you make the horizontal spring too short or weak, it won't do anything at all, as the big vertical ones will carr all the weight.
I don't know what springs are most influential on the ride height. Given that it is easy to remove the compensator spring, I was going to remove it, go for a slow careful little drive to settle the height, then check the height. Then put the 190D (less strong) comp spring in and see where that gets me.
But once again, you cannot raise or lower the car without getting camber change.
Good luck, Drew
