I don't know what changes you have made other than tires to combat the push you (sort of) describe, but keep in mind that the tire is the most coarse change you can make to the setup. I would think that finer adjustments like changing springrates or shock tower position would cure that, if the next step in tire is too great of a change. Using other people's setups will get you in the ballpark, but some fine tuning is usually required to suit your track conditions and driving style.
