Help needed with e39 M5 Wheel Alignment

[TimInNOVA]

I took my 2001 M5 (79,800 miles on it) to a local tire store to get the wheel alignment checked and I have a few questions post-results.

Prior to this the car went down the road true and straight, but the outer-edge of both front tires are showing considerable wear. Back in August I replaced the thrust-arm bushings due to steering wheel shimmy over 40MPH, and that solved that problem. I thought the wearing on the outer-edges might have been caused by the worn thrust-arm bushings (that is one of the symptoms as I understand it), but I thought it could also be caused by a bad case of toe-in.

I've attached a copy of the alignment print out.

1st question: What would cause my right-front wheel's caster to be out of spec? A worn bushing or possibly a bent strut? I know caster is not adjustable, but I figure a good mechanic might be able to move the strut or something to help this out.

2nd question: My rear toe looks very out of spec and I want to get this and the front caster adjusted, but I want to take it to someone that really understands BMW e39's. Can anyone recommend a non-dealer BMW alignment guru in the NOVA area?

Thanks,
Tim
