Well I also think that the Alpina B5 Edition 50 used the X5M front calipers and rotors. They look identical and the size of the rotors also matches so you def have the right setup in front. I'm really just intrigued though as to what caliper and carrier combo the B6 took as normally I would have thought Alpina didn't design their own brakes and used from existing options within the BMW lineup.
