I'm not talking about the rotors, but the calipers itself.
Both blue ones are different. My guess is that the left one (with the m logo) even might house a larger pad.
I speculate that the left one is an e60 m5 caliper with dual piston, or maybe even a dual piston 7 series. The other one is 335i
You can recognize those dual piston calipers at the 2 extra slots (they're not going all the way through though) either side of the center slot where the wear sensor lead goes through.
AK72 saw that very correctly.
