I notice the calipers looks to be the same just different colors. But I assume the M sport brakes are 374 mm for the M550i as it is for the 540i, but the M performance brakes are 395 mm.
So how can the same caliper fit different sized rotors?

Why do you assume 374mm ?
The M550i comes standard with 19" wheels. This may be because of the brakes.
So they may be 395mm standard.
