I know its an old thread and its been a few months since the last question but i just got done reading the original thread on SF and feel it would be helpful to post up what little I found for the mkiii.
*Rear tophats don't cup the new upper perch the way the fronts do and aftermarket pillowball tops are needed.
*Shock damper body is said to be too long the get much drop without bottoming out. The shocks can be sent out to be shortened to fix that issue or cut the bump stops short enough to stay off them.
*Spring rates didn't seem to get ironed out but 650 front and 400-500 rear sound like good starting points for a street setup.
*2.5dia springs work all around. General consensus seems to be run 8" with helpers.
It's unfortunate that the people that had actual experience with this setup all disappeared before revealing the secrets.
