From my limited understanding... all from Pirate4x4 reading... Triaged, ErikB, and Booger_Weldz are the guys to talk to...
I think you are going to want to bring your AS down in the 50-60% range and then play with it from there.
A good rule of thumb for finding quick CQ without measuring too much is to use the top bellhousing bolt as a reference.
Also, get your RA down in the -1*to -2* range to make it handle better at speed. Roll Oversteer can get SCARY quickly...
Personally, I would triangulate both uppers and lowers for more lateral stability, or run a 3 link with a panhard. 4 links with panhard have inherent binding qualities if you run joints with little deflection.
... but really, if you want to get spot on, you are going to need corner weights and also more numbers with your coilover inclination and mounting in respect to your links and axle.
...or you can just stab at it in the dark until it "feels right", the more information you get yourself the less you have to "stab"
