Ja, there are size differences.

X5M/C 6-pots versus 2NH M Sport 4-pot but they'll bolt on differently:

"G05 calipers bolt directly to the hub from the back...... F95 calipers bolt to a bracket from the top, which then bolts to the hub from the back.

BMW will not sell you those brackets by themselves.... they only come as part of the caliper."


Front rotors are 395 x 36 on both but rears are larger on X5M @ 385 versus 2NH 375 x 24

A forum member upgraded their 2NH M Sport brakes to X5M and documented the process starting with this post:

Thanks for the info. Sorry for the late reply. I pulled the trigger back in February and ordered MY22.

I'm trying to verify that the below are the correct ceramic pads before I order. I have a 2023 X5 45e M Sport and nothing really computes when I put that year in, so I put 2022 X5 M50i and I get the right pads (same calipers if people didn't know). It shows that it's good for my vehicle with the M brake calipers and wanting to double check.

Hello fellas. Sorry to dig this post up. Hoping that one of you gurus can quickly help me out. I'm selling the factory front brake calipers from my 2020 F97 X3 M to a gentleman with a 2020 X5 X-Drive 40i.

I know he has the non M-sport brakes up in front. Because I looked up the RealOEMParts digram with his Vin # & it says he has the 348x30mm rotors & not the 395x36mm rotors that my X3 M came with.

Other then larger rotors, is there anything else he may need for this to be plug & play... ? His dust shields looks to be exceptionally huge & real hoping he doesn't need some (impossible to find) adapter bracket. THANK YOU in advance... !

I haven't done the conversion myself so I can't speak from experience but judging by the contents of the official retrofit kit that BMW sells, part number 34112458883, he will need more parts than just rotors and calipers. Take a look here at what all is included with that kit: https://www.bmwpartspros.com/oem-par...ed-34112458883

Thank you man. I've seen that kit before. But technically speaking, from the diagrams & part number look ups it appears there's a much simpler, easier & cheaper (to a certain extent) way to upgrade the front calipers. The ones I'm selling are also an option that's on the table. Can someone please verify no additional brackets are requires to make this work.

Do the F97 X3 M calipers work as a direct bolt on to a 2020 X5 X-drive 4.0 with thing more then the larger corresponding rotors... ?

Right now I have some serious buyers lined up & need to know if this (the F97 X3 M front calipers) is a direct bolt for the 2020 X5 X-drive 4.0 Any word yet on this guys... ?

Where I can find those technical details pls? Where are documents pinned? Thank you
