Ran with the dropped gearbox, centre insert, lower inner show tower, outside hub hole.

What effect on roll centre does this mod have? If moving the top ball down raises the roll centre, does moving the bottom pin up lower it?
With moving the gearbox down, and the wishbone pivot location up, do you need to move the top link up a bit also?

Raising the pins 2mm will raise the roll-centre quite a lot, so will make the rear loose through the corners.
For maximum rear traction you'd want to lower the diff and lower the pins (sounds like that's how you had it before?). Lowering the diff will give more rear traction on the power due to the extra angle on the driveshafts (it works a bit like anti-squat).
