Maybe I'm used to my 330 but it feels like I'm always working the keep the back end in the back.
I am in the same boat. Stock suspension w/GC plates -1.8 back, -2.8 front camber. Before the car would plow and I would hammer the gas at track out (slower speeds at steady state allowed for full throttle exits).

With increased grip, the rear is traction limited at track out. Thats the only place I see track out. Instead of reducing camber (front grip to compensate or negate to rear grip), my suggestion would be to run wider rubber at the back. I have a square setup now (275 Toyo R Comps) but will get a pair of 295 for the back.

We ran a staggered setup in the GT4 Vantage N24 and the car was much balanced.
