The stiffer rear sway bar and stiffer springs should help the car behave at the limit.

I think youre lifting the inside front because your rear spring rate is too low. That is where you should start before you go changing anything on the front. The soft rear is very apparent in that pic.
Also, take into consideration what moving to a stiffer spring will do to your droop travel. You typically want 60% bump and you may end up with 0 droop travel.
Moving to a stiffer front spring might also put you in a position where those 255s are no longer enough tire and youll just end up dialing in understeer.
