Defeating Initial Oversteer

I need a little tuning advice here.

The basics
2004 STi
Ohilns shocks all around - adjusted to fit track style
Stock springs
RCE front bar set to full
RCE rear bar set at mid-level
Whiteline Camber plates set to 1.8 deg and castor maxed out
235/40/17 on stock wheels - running STU so no race tires

I'm getting this annoying initial understeer in corners. Once I get into the corner I can modulate throttle and get the car to rotate nicely. It's very controlable mid corner and on exit so I don't think this is a left foot braking issue. I could dial up the swaybar in the rear, but it seems that would only help with mid-corner rotation.

Is more (-) camber the solution here?
Any suggestions welcome. I cannot toe the car out as it is a daily driver.

more camber up front and yes, some toe out in the rear.

Even 1/8" total out will be helpful. The tire wear should wear out the insides faster then the outsides, but c'mon now... tires are a wear part, USE THEM!
