try what revlimit suggested. given everything else is not affecting handling that much. set the sway bar adjustment in front towards the inner holes for stiffer and the rear towards the outer hole at the end of the bar for softer. this will surely force the front to comply more to ur turn in given u don't just stab the brakes. the rear should have less torsion letting it brake lose under weight transfer. if anything, ur understeer will at least lessen.
as for me, i'm ok...and have no choice in having some understeer in my car. besides, its an open diff model...so no point in trying to do crazy drifts here. my tail wiggles and more throttle will just upset it more. hope you can find an comfortable setting that suits you, or one that you can tolerate.
