Bob - I read this as you want to control jacking.
Trivia -
If one believes the car rolls around the geometric roll centers; at 3 degrees of roll, the front has moved laterally 20 inches (still inside the ball joint) and the rear has moved 1.5. Our roll axis is now at a significant angle (in plan) to the mass centroid line which does not intuitively seem like a good thing to me.
If I did not want to run it so bad, I would seriously look at moving the front inner pivots inboard .5 inch and lengthening the arms accordingly.
.5 inches cause it looks like it could be done
and it would cut the difference by half.
