It's always a balancing act, more camber= better corner grip = increased roll= less camber= more camber needed = less contact patch on road on straight = more twitch on turn in = more toe in to counteract, but with diminishing results.
Then it goes wet and you need to start again .......
Then there's driver preference for over/understeer before imminent disaster happens.
Well worth playing with rear settings as the more you can get the rear to shoulder some of the responsibility for keeping the car on track, the more you take off the already overworked front end, which is having to deal with all of the acceleration force, most of the braking force and steering forces, so getting the rear to help a bit, helps the overall picture. Lots of issues at one end of the car can be caused by the opposite end.
