Thought I would dig out the official bmw info from TIS, here is the alignment for Msport/lci although thee is little variation.
Here's my interpretation/ my personal preferences
Front
7mins front toe in each side (I like 4mins)
.54 degrees camber. (to change camber you need to film the pins from strut mounts, I like around 1 degree)
Rear
9 mins toe out each side ( I like 5 mins)
1.8 degrees camber
Biggest factor is the operator and care and attention, a good alignment need to be checked for consistency by aligning, driving up the road and then rechecking. Rinse and repeat till consistent
