I've seen no unsual wear patterns. I do rotate the tires when I do an oil change (every 3000 to 4000 miles).

For street use, I think those settings are right in the ballpark.

Any time you change front settings you should do the rears too to make sure the car is 'aligned' . Changing the toe just slightly can throw off the thrust angle.

I used .25 front and rear camber with 0 toe and 3.5 degrees caster for more feel with the sport ratio rack that i love so much.

Also remember that the c4 suspension needs to settle after driving. if they jack up the car at all ( some alignment machines have mini lifts that lift the center of the car to install the alignment spiders on the wheels) it will throw off your alignment when driven and the suspension settles. you have coil over so you may not have an issue here but with leaf springs and even with custom length Bilsteins i had to pretty much align the car with +.25 camber all around because when it settled it would read -.25 (this is why stock c4s have positive alignment settings stock).
