I agree, as long as toe is set to spec you wont even notice any tire wear difference. I had my EG dropped 3 inches all around, toe was out for about 4 months and I noticed tire wear. Fixed only the toe and they were good from then on.

 

It takes a LOT of camber to hurt your tires. You don't need a camber kit. Hell, you could probably be dragging the bottom of the car on the ground and still not need a camber kit.
