from what I recall when I ran barcode fronts versus scrubs fronts, the scrubs gave me more front bite, I even went with the barcode fronts as the scrub fronts gave me too much steering in comparison to barcode rears (they were great with switches though). Not sure if you open to trying a different front tire.

Have you tried less shim(s) under the front tower ball stud? In general if I felt the rear end was good, I played with the shims under the ball stud on the front tower to adjust how much bite I was seeing up there. It may be that little change could give you what you need but still keep the rear feeling "right" for lack of a better word.

Just some thoughts, could be way off base here but figure the change is quick if you haven't already tried it.
