I think I said it in the original thread. The standard system is twice as stiff in bump as it is in roll. That’s not where you want to be. The way round it is a split system, but the effectiveness improves with the distance apart of the two pairs of discs. So, mounting shortened arms to the original damper mounting points doesn’t achieve all that much. What you need to do is use standard damper arms and space them so the ends mount to the radius arm ends. Then you will see a difference. The immobilised link is a different thing entirely. Essential, but nothing to do with dampers.
