Cyril, that's not from camber... thats the tire rubbing on the suspension bolt from the upper arm, i had to shave it of with a die grinder to on my recent install as it was making contact cause i have a wider tire... the combination of the camber and lowering is making it rub on the bolt.

when the car is on a jack it was not making contact but when i put it down it did just slightly... that wear is too extreme to be a camber issue...
