Stance SC-5 on a 2012 G37S doesn't fit
 

I just received a set of Stance SC-5 20x8.5 +35 front and 20x10 +35 rear. I have a 2012 G37 sedan journey with S-package which has a big break package. I have dropped the car on eibach pro kit springs and ichiba camber kit front and rear. Just got the rims today and the front wheels will not even mount because they hit the brake calipers. The rear sticks out of the fenders just a little. Does anyone else have these wheels and what size and offset are you running. Need4speed motorsports said I needed to order the +32 offset for the front instead of the +35 but I don't see how that would make a big difference unless the wheel is designed different because that is only 3mm.

you can solve this problem by getting a slip-on spacers

Can you tell how much space you need to clear the calipers? 3mm change in offset doesn't sound like much of a change if they're already hitting. Spacers will solve the problem but may put the wheels too far out for your liking. If you can return them without taking much of a hit in the wallet, you might want to do a bit more research then re-order wheels that won't stick out in the rear and need spacers up front, that's what I'd do.

I ran the 20x9 +32 front and 20x10+35 rear and it fit fine.
