Default On Power Understeer

Ok guys i have been noticing this the past few weeks and i would like to know what some of you guys did to correct this....

situation:
entering in the turn is fine, right after the apex trying to power out the car all of the sudden has allot of understeer. Front end starts to point in the other direction.

If i take the same turn but apex later cuasing the rear end to kick out a bit then counter it's fine but i can't put the power down early

forgot here is my setup...
Advan RGII
18X7.5 ET 48 225-40-18
18X8.5 ET 50 255-35-18
Bil PSS9 Set @ 8 front 8 rear
Corner balance is 50/50
F/R balance is 47.8F 52.2R

i don't want to stiffen the shocks too much because it's a daily driven car. i just want to correct the understeer.

any sugestions??

I get this too. I think it's new to AP2's or 06's. I have to end up throttle steering the weight so it shifts correctly and the same happens as you said.

The solution would be either non-staggered wheels, stiffer front sway bar, or lower spring rates on the front.

i was thinking of a stiffer front sway bar but i think that might alter initial steering response?

i love the initial steering response now but follow through sucks when your on the power.

you can do a stiffer damper in the front and softer in the rear to get some oversteer... sway bars can help ya out too

Maybe just keep adding gas to get oversteer?
