I like to have a bit more camber when I put more roll into the car. Maximum forward bite is at the middle of the tire, not the sidewall, so when the car is rolling hard in a turn, not having enough camber seems to remove even more corner speed. In some conditions this can also cause traction roll, because you overwhelm the tire's sidewall and it "gives" out.

With the car on the bench, turn the front wheels and lean the chassis like it would in a turn. This will help you visualize it. Mid-corner you want to maintain your contact patch. Too much camber can cause it to be loose..... since you don't reach the maximum contact patch while the tire is fully loaded, the force overcomes the grip.

Sorry, it's tricky to explain
