I guess the length of the camber rod is affecting this, but I run middle hole on hub (no mod) and one washer under inner ball stud and if I need a little more traction I go to two washers. I even run the 3.5° hub for additional bite in the rear compared to stock 3°.

Raise ball stud, more traction per the manual and my seat of the pants experience. Higher ball stud = more chassis roll per AE.

But thats the opposite of what you are saying above...
