The weights for unladen on the rear axle is 939kg and for fully laden on the rear axle is 2100kg. The diagram shows that you have to have a fixed amnount of travel for the different axle weights for the correct pressure distribution. So you would have to move the attachment point of either the LSV or the contact point on the axle the same amount as the lift so tha the lenght of the bar and the travel for the different axle weights stay the same. That you will stay legal as well as safe

Yes, quite right. That's what we have been discussing. Difference was that I suggested to bend the rod and Louis extended the attachpoint.
Louis though has a point in that it's better to extend the attachpoint - certainly in extreme situations.
But what you're on here is what I touched as well when I said that the characteristic of the new spring is important as well.
In case the new spring is stiffer then the original spring, the body won't sag as much with a certain load.
The LSV will only set the right pressure if the rod has moved the right distance - or better - the right angle. So if the new springs are stiffer than the old ones the attachpoint on the axle should be moved towards the LSV. That way the angle can be kept the same with smaller movements.
One would need some investigation to get it all right tho.
