Uh... Camber is non-adjustable on our cars... At least, not through conventional methods, and not without camber plates. The ghetto method would be to loosen the top strut mounting bolts and push or pull the top of the wheel and then retighten. I was able to get about 1.2deg of negative camber on my stock-suspended NX2000 that way. Toe, however, is adjustable by way of turning a nut on the tie rods.
Camber doesn't increase tirewear... Bad toe settings are what kill tires. Get an alignment done and have them set the toe to zero or 1/16" total toe-in. For better turn-in during corner entry, then I'd suggest about 1/16"-1/8" total toe-out, though tirewear would be questionable with those settings.
