Craig,
Your numbers appear like this:
LF 514
LR 845
RF 509
RR 739
It looks like your LR is carrying a little too much weight. Does it sit higher on that corner as well?
The way it appears now, the LF/LR proportion is 61% and the RF/RR is 69%. You should aim for approximately the same L vs R side. Once the side-to-side proportions become closer, the diagonal weights will follow.
Try lowering the LR to transfer some weight to the other corners, then continue adjusting ride heights until you get closer. I know, resetting rear height is a b*tch.
What are the current corner heights?
