you mentioned that you have your front set 2 clicks stiffer than the rear, but you don't have a reason for doing it. remember, the suspension already comes balanced with the front stiffer, so start with matched settings. a stiffer front will make a car more understeery, so matching the settings should help. I have an 8k/7k setup, and I actually bumped up my rear more to make the car feel more neutral under power. I run with even hot tire pressures all around (38 on track), -2, -1.5 camber.
