hahaha a few days ago i just noticed my camber was out of alignment. supposedly it is in fact better, yes better, if your rear tires are "butterflying" b/c it will aid you in conering. (note: only if the camber is ever so slightly displaced). yes it will wear out the innerside of your tires quickly. i brought up the same question to a buddy of mine yesterday and he owns a boxster. he showed me his car and his back wheels were doing the 'butterfly' --> / \ he said it came like that and its normal if you lower a car for such a thing to occur. hotchiks sells a rear camber alignment kit.
