In VTA, I've been running the square mount on the front of the rear a-arms (stock) and the circle mount on the back of the rear a-arms. It gives me somewhere between 1/2 & 1 degree of rear toe. Unless the grip level is very low, the rear of the car always feels pretty good.
I had to add an extra shim under the circle block to level out the hinge pins/a-arms in the rear.
