The rear (compared to my 19" x 9" wheel with ET25) will have 29MM less inner clearance and push out an additional 9MM - mine are sitting very flush right now (maybe even poking a bit) - so I think 9mm will poke some.
If you are active on IG take a look at BFilty8 (I think he is on here too) he just put 20" FF10's on his M340 and could likely help you out with specifics. He's part of a G20 group chat I participate in and I'm confident would be happy answer you directly if you DM him with IG

Thanks for the great help!
I have messaged him on the IG and hope to get some reply.
Also I have email-inquired the following garage who also got a G20 320 installed with the 20" FF10.

since my local sales can only provide 10.5 for the rear so I really hope they do fit with no concern eg. too close to the suspension / wheelwells. I don't care that much if it does poke out, I might even like it, who knows :P
Didn't realize there's so much to learn just to upgrade rims lol
