There is a good post on here by someone that describes the rear camber problem with our car when weight is transferred to the rear. He mentions doing a burn out, and then measuring the width of the tire mark. It will indicate how much of a contact patch you have with the ground. He basically proved to himself that a good portion of the rear tires was not touching the ground due to too much negative camber.

The cure for something like this(besides building new control arms) include:

Way stiffer springs in the rear. Probably want to be running 12K+ springs in the rear.

Corner Balance the car, and as mentioned, raised the rear to distribute the weight and get it over the tires. Think about the drag cars you see on TV. Driver in the rear, all the weight possible over the rear tires.

suspension should be setup 40/60 on your shock travel, 40% for compression travel 60% for rebound.

Smaller front tires, less friction up front. Swap em at the track if need be.

You need weight over the rear tires to increase static load, this is accomplished by raising the ride height of the rear coilovers. If you are on stock suspension or even just lowering springs, it's not going to cut it.

Once the weight is over the rear tires, need to keep the rear arms from moving and cambering the tires out, you do this by using stiffer springs in the rear, and then dialing in the rebound.

EDIT: the other single biggest thing you could do would be installing a proper differential.
