Well doesnt it matter what you do with it. If you like to do autocross aka turning circles on a empty parking lot then you might want less camber and maximizing the contact patch for low speed. If you drive a track like the Nordschleife with high speed corners, elevation and camber changes then you need more camber. I'm at 1º,1' front and 2º,25' rear. I went up on rear camber from 1,55º and the new setup feels better to me. Toe is set at near 0 front and rear. If anything I would probably try a stiffer front antirollbar now to kill some roll in the car.
It still does this, so I certainly not too much rear camber I think:
