Basically bolt-on, only modifications required are
2mm washer,
cut the dust shields from bottom side 2-3cm,
cut the brake pads from bottom side ~3mm.

I used the 7 series G11 740i 2017 unpainted calipers and painted black. Will but some sticker there aswell.

Thank you for sharing this! Any part number for the calipers? Did it require new brake lines?

Right now used the old brake lines that were on the e92. Probably upgrading to braided lines when next brake pad change comes - right now used the same pads that came with the used 7 series calipers, half worn pads for testing.

So far ~400km the wear on the disc is even - on top side of the disc the lip/wear continues from the same spot that the original e92 m3 pads touched so ~1mm from top. On bottom side where the pad was cut they go over the disc little bit so no lip there anymore. With new pads i can use them as template to get correct size pads.

I used G11 7 series 2017 non m brakes. (not painted calipers)

The M brakes on 7 series are bigger (the two cylinders on front of the caliper have some room). This video is very informative but misses the non painted calipers, exactly the same but not painted.
