Wheels offset

I have been asking this question everywhere but I cant seem to get an answer, I am hoping you guys would know since the f12 has the same stock offsets as the gran coupe.

Stock wheels are 8.5" et33 front and 9.0" et44 rear. I am looking to put on 9" et35 wheels all the way around. I am wondering if they would A. Fit wih no issues and B. look ok in the rear since its a 9mm difference.

My first thought is that 9mm is nothing, but after reading about other cars it seems like a 9mm difference could be an issue.

DJ, I hope that what you are suggesting is right as I bought four 8.5 inch x 19 wheels with + 35 offsets (with Blizzak LM 60's) to use all around on my 2012 650 I x-drive convertible as my winter wheels/tires. McBucky

I never did get a direct answer, but using this tool it seems like there shouldn't be any issues.

Temporarily put one of your fronts on the rear and mentally add another 3/8" to the rim/tire plane and see how you like it
