I agreeMr.Yamauchi why we can to adjust negative camber angle,but we are not able to adjust positive camber angle?
This is the most effective way if you want to reduce the rear end grip.

It's not the same.why not just use excessive -ve camber,
as the suspension compresses you'll get even more -ve camber and even less grip
Here's the car and tires.Car? tyres? race style?
Why do you want mid-corner lift-off OS? by then you're touching the apex and should be on the power..
Surely stiffer rear springs, LSD settings, ballast weight and roll-bar adjustments will loosen the rear end
the question is why do you want to remove so much grip on a race-car..?
