    The Toyota dealer only did the front wheels and did not adjust the camber since it was within their spec range in the end.

    I might just try to find a local shop that can do the alignment right and with my specs.

    Back when most cars had positive camber (front wheels leaned out at top), we heard that to avoid tread wear we needed toe-in to compensate for the wheel's tendency to roll in a curve toward where it was leaning. Now we have severe negative camber (Prius rear wheels: neg. 1.5 degrees, plus or minus 0.5). This suggests that we should have toe-out to compensate. Instead, Prius specs call for slight toe-in. Might this explain the many complaints of excessive tread wear? Has anyone out there experimented with shimming the rear wheels for toe-out? If so, how much toe-out would be appropriate for the specificed camber?
