Hello mate
Maybe i can answer on your question because i have tried it allready, after i saw your setups (of course)
.
I tried it on the Porsche aswell, i also tried your setup and compared it to mine.
Afterall: To make a real quality Camber setting, GT Sport dont give us enough information, to setup the camber in quality. Because u need telemetry of the wheel during cornering (even rfactor had that: U saw the tire in 3 pieces during ur test driving...the temp inside mid and outside). So theres the only way to setup that with knowing how it works (kind of) and to feel it on track.
Normally you try to put as much as possible for good and direct corner entry, but less as possible for less tire wear.
Of course i tried it to drive with 3.0 camber and with 0 and the tire wear was comprehensible and the fact that the inside is overheating...i dont know i havent felt that, but maybe iam wrong. I also tune the the camber for more stability during cornering and for that i lower the toe on the rear to have more cornering in fast corners. Because of that i can also add lower LSD to have more power out of the corner because the more negativ camber on rear makes also more stability out of the corner.
Only negativ effect: maybe a lower top speed
So your setup is very good and stable, but i feel like that the car dont really want to follow my steering inputs, can depend on driving style.
Iam pretty sure my setups are not for everyone aswell but at the end i try to manage a stable car which you feel it want to go to apex if YOU want it
But at the end i would suggest a bit camber, depends on car of course, but iam trying never to go under -1,5 front and -1,0 rear...
for me this values feels the lowest limit
i hope i could help you mate and answer to your question
