Proof here that the F95 X5M 6 pot calipers and 395mm ///M discs are bolt on fitment to G2x (and most other G series models too).
The 6 piston calipers are the same as used on the M3, M4, M5, M8 etc. The difference being that on the other M cars, the hubs have studs on them to mount the calipers, meaning that to fit them onto non-M cars, you need a custom made bracket.
With fhe F95 calipers though, the hub does not feature such mounting and BMW have had to make an OEM caliper mounting bracket to make them fit.
After careful cross referencing of parts - I was confident that this would make the F95 set up bolt on fitment to the G2x etc.
I bought these calipers and discs to check and sure enough - everything is good to go. The only consideration is that the disc retaining screw does not line up, but that would not be an issue once the wheels were bolted down and torqued up.
Just need to decide what to do with these now as I don’t even own a G series 😂🤦♂️ I’ll either sell them on or keep them until I buy a G21 LCI!
