these are the part numbers for the repair:
4 41-21-7-198-335 roof rack bracket
7 51-13-7-217-789 clamp
5 51-13-7-184-575 clamp
4 51-13-7-232-420 clamp
?? 07-14-7-207-986 torx bolt
that is all the info on the SO. They told me it also required a special adhesive.
I noticed on our showroom that the pre-2012 models already had the brackets. ironically a 2013 Alpina had them!
