If you are running a lot of negative camber, toe OUT actually inproves tire
wear. It also contributes the kind of darty handling that autocrossers enjoy.
In the olden days, car makers enhanced stability with a lot of toe-in which
they balanced for tire wear with positive camber. Not so great for cornering.
