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
