Also, probably just not needed. I believe the front e92 was floating caliper.

Electronic handbrake is the cause. Do an image search for electronic handbrake caliper and you'll see the mechanism they use.
Same reason why Ferrari's, McLarens etc have the main big caliper and a small additional sliding caliper at the rear for the handbrake.
