Why Camber does not eat tires...
it does. Caster dosent nor does SAI but it can cause a less desirable steering situation. I love the write up. I am finishing my HFP set-up and alignment. I'm going to try negative camber set up. but maybe 1/2 degree... instead of 1.5 too much negative camber is murder for your tires.
3.5 neg camber... like riding on bike tires on the inside. the goal is to have the tires meet the surface of the road. when a car squats during a turn is when the camber really makes a difference.

just a better understanding of camber. its like walking on the side of your feet. positive toe is like duck feet, negative is like having your feet pointed in. Negative caster is like walking leaned back and positive caster is like walking leaning forward. Just a quick reference...
