Would M wheels fit?

[BartekF]

Hello,

Recently got my F13 650 with 18” winter tires so now I’m looking for nice 20” summer wheels. I want to buy those new from M6 Gran Coupe and here is the question: would those wheels fit in my car?
I asked at BMW dealership but they did not know – finally answered, based on catalogue that wheels do not match…
Has anyone tried to put M wheels on 'normal' F13? I see, that wheels from M are a bit wider than standard ones: 275->295 rear and 246->265 front. ET is different as well...

Thanks,
