So I did move the ring about an inch down from the perch to raise the vehicle by using an oil filter pliers and the spanner wrench together, but even after moving the ring by that much the height hasn't changed at all.
I was doing some research online and
is basically saying that the whole thing has to come apart so the shock can match the springs length with 5-10mm preload.
Do I really have to drop the whole LCA do adjust the height? I thought I saw a few posts up about how the height can be easily adjust without taking anything apart...
