I don't know much about this stuff you understand, but I have this corner weight spreadsheet and I put your numbers in it and I see your LR is carrying a lot more weight than the RR. Compared to many I've seen, your LF is quite a bit heavier than your RR.
I didn't see where you said what was actually happening, is it pushing, is it loose or in a complete drift?
If I ask this too much it's because I think it's important. What is the turn radius, is there banking, and what is your stagger on the rear?
