Sorry, just saw this question. Not sure if you can retrofit the F85 front calipers to an F15. This F15 M Performance BBK uses the same size front (395x36) and rear (385x24) rotors as the F85, as well as the same rear calipers. The front calipers are a different part #, so we're not exactly sure why or how fitment would be affected. If anyone on here as successfully retrofitted the F85 components to an F15 - please chime in and let us know how it went. Also, the cost to piece together the F85 components would be much higher than the cost of this preassembled kit from BMW....something to consider.
Oh thanks for the reply. I know the cost is much different as going from 4 to 6 pot calipers up front and the rotors being performance vice just larger. And I know many have reported selling the MPBK rotors back and buying the F85 rotors since they are the same size as you mentioned so I was mostly curious about the 6 pot calipers compared to the 4 pot.
