Add camber up front. Changing springs and bars and dampers is a waste imo if you're not even using the whole tire you've got. Stock suspension I think I went up to 3.2 degrees and the improvement in grip was immense.

Technique will do a lot, newbies generally charge the corners too hard and create their own understeer, I have definitely done that. Instruction/tightening the nut behind the wheel can cure a lot of car setup problems.

The other trick may be pedal dance to improve trail braking rotation. After exploring those things I think a stiffer rear sway may get you the balance you want, but I'd chase alignment first, I was pretty happy with the balance with -3.0 degrees up front and nothing else.
