DO NOT use a BMW dealer for alignment.
I saw a blowhardy comment about how 'only BMW dealers know how to align BMWs'. Nothing is further from the truth.
I started a thread on alignments:

If you go to a dealer they will set it mid spec, and tell you 'thats just the way BMWs are, its _______".... and in the blank, insert: stiff suspension; performance; racing history; handling; blah blah blah
Set your toe to 0.01 to 0.02 each wheel
Set camber to mid spec. You can tolerate a bit more camber up fron with the 50.
Set your inflation pressure up front a bit higher than the door- like 2psi more.
Thats it.
