Probe too loose!

I'm currently running a Probe on a 1/4 mid bank asphalt, and I'm having a problem that maybe you can help with.  My car launches coming off the corners and can hold just about any line on the track, but for some reason on entry it's breaking loose, BAD.  I messed with tire pressures, sway bar, tire sizes... nothing seems to help.  I'd like to be able to dive into the corner, as that's the best way to pass at our track, but I lose it almost every time unless I slow way down.  Are there any adjustments you can think of?

Currently I run 175/65 on the left side, 185/70 on the right.  Tire pressures = LF30, LR25, RR20, RF35.  We are allowed just 3/4 RF camber.  These are the settings I've always used for max performance, but since a wreck last year it's been loose, even after replacing all bent/broken components.  I'm at a loss, does anyone have a suggestion?

try lowering the LF tire to 20-24, LF to 30-32, LR to 20
RR to 25
i run similar on my cavalier and with a civic for best results so far, we go 60 series all around and maybe 70's on the back to pitch the car better(still testing its our 3rd week with the cavalier) but raced the civic for a few years and others for 15 years
