Congrats! Almost the same as my setup (I also have GT3 lower control arms)
Let me know when you have figured out how to setup your car, I am still struggling with the multitude of setup options I have now
To compare setups:
front -2 degree negative camber
rear -2.5 degree negative camber
rear 1/8 degree toe in
front sway bar: in the middle
rear sway bar: 2nd to softest
PSS9:
front 3 (1 is hardest, 9 is softest)
rear 2 (1 click harder than front to compensate for the 46%/54% front/rear weight distribution
Corner balance
LF: 740
RF: 740
LR: 880
RR: 860
