Did you manage that without alterations to the wheel housing at the back?
I just booked a track geo for my RS with the Black Falcon race team in Nürburg. They have a couple of road GT3's and one RS. I was told that they could not achieve ideal camber, which they reckon is 3, on the rear due to the 21 inch wheels. They have been testing at Ascari and Portimao over the winter and were able to get much more performance and tyre durability from the std GT3 because the car allows more camber at the back. They are now looking into how to address this, but expect it cannot be achieved without altering the wheel housing.

Yes, there is no issues for regular average track setup. But for ideal set up wheels are too big. You can not drop it as low as regular GT3. When you put more negative camber your car also drops down significantly

No modifications?
-2.7 rear is fine for Dunlops, -3 would maybe needed for Michelins due to only the outside of the MPSC2 wearing.
A big help is running the car stiff PASM and IMHO the rear sway bar should be full stiff for max tire wear and a more stable car at hight speed cornering.
Porsche did install new front fender liners, now no rubbing with -3 front.

My car is unmodified. Need to keep it as much as possible due to local regulations.

Quick update. Bought a digital angle meter, built a simple camber gage and took some measurements of my camber. They are between -1.5 and -1.6 all around front and rear. That looks about right from my eyeball meter as well.
