funny thing the rep. is really sure they will fit but some of the comments above states they won't (rear wheel is the main concern)...

I did use some rim/wheel websites to do the math on the difference of the 792M (OEM) and FF10 and it does look fine to me...or am I missing anything?
Your front will be just fine...it is the same width and offset as my HRE's (albeit with a 20" wheel vs my 19"). That said I am running a 5mm spacer in the front making my adjusted offset ET20 - and I am going to test fit a 10mm spacer which will make it ET15. They will sit quite flush.

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.

http://www.bplus-bmw.com/blog/diary.cgi?no=8085

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

The gentleman from IG is in fact running the 20x10.5 in the rear (he got back to me last night) not sure on his tires though. Looking forward to seeing your car when it's done - the FF10 really is a spectacular looking wheel IMHO.

ps- are you going with the standard silver finish (like me) or something a little more interesting?

Yeah he replied to me too same rim setup but different with tires. He runs a 245/30/20 and 275/25/20 and lowered with H&R springs (1.3" lower both front and rear)

Mine will be 245/35/20 and 275/30/20 and planned to lower with Eibach springs (30mm front and 25mm rear)

After calculation there might still be some clearance issue for the rear but we'll see!!!

My G21 m340i Touring is in dravit grey and the rim is the FOG (satin charcoal), very greyed out combination. Hope they look good!

I don't want a "flush" look, but less tucked than stock would be nice. I also like meaty, not stretched tires
Almost running that setup.

(F) 19x9 et 25 - 255/35-19
(R) 19x9.5 et 45 - 275/35-19

No issues with rubbing at all on a RWD m340. Was previously on the square 19" 792M setup.
