Keep in mind that the alignment warranty coverage is 2000 mi or something ridiculous. If you think the alignment might be out of spec you should get it checked sooner rather than later if you have any hope of getting coverage for the alignment. They may find it to be within spec but I would then have them then align it to more tire friendly settings if you are concerned with wear. My wife's toe was 0.9 & 0.7 deg from the factory. I had it set to 0.1 deg. I also had pretty severe rear wear from the negative camber. It was out of spec (as measured by the dealer) from the factory but it was more positive than it should have been. I actually had them go a little more out of spec to help with the wear. The handling feels nearly identical but I don't drive it like I do the M3. Wife hasn't complained about the handling so I guess that is what matters.
