Hi everyone,

I'm new to the forum, my name is Mattia and I have a 2018 Bmw F20 125d. I don't know if it has already been discussed as a topic, I would like to upgrade my front brakes with the 380mm discs of the Bmw M2. I currently have the original Msport basic brake system 340mm front and 345mm rear. Can someone help me and tell me if it is possible to make this change? What do I need besides discs? I know the 4 pot caliper is the same.

thank you all

No, it's not: F20, M2. (Sometimes part numbers differ only for looks, actually interchangeable, but I would doubt it's the case: these look pretty much the same , would they bother only to cut 34 grams off?)

Notice that M2's 380mm is even larger than F20's M Performance 370mm. This is what you need if you really want it: Set of M Performance brakes front/rear.

Thank you so musch. I will provide to buy two new front calipers for 370 mm disc.

I hope you did not overlook the warning: "For replacement/repair only, not suitable for retrofitting as brake kit!", regarding the parts.

Well, wondering what that warning could actually mean besides front/rear caliper colour mismatch, I recalled/found this thread: https://f20.1addicts.com/forums/show....php?t=1848948. So the warning might be serious for basic non-M-Sport brakes enhancement and negligible in this particular case.
