One piece of information that is missing is the amount of camber you are running. Don't go too extreme of course but if you are having a bit of wear on the outer parts of the tires but like the handling with the camber link position, try leaning in the tires a little bit. Up to 3 degrees. Keep in mind also that with different amounts of roll stiffness, the tires will react differently. One setup may favor a softer foam insert where the other favors a firmer one.
