Hey everyone, this is my first post on here as I have just recently acquired a 2013 G37x. I ordered a set of wheels (19x10.5 +22 Work Emotion ZR10 with 275/35/19 sized tires). I compared the fitment of others running a similar setup and based my decision off of that, however now that I have the wheels here and test fitted, they seem to poke a crazy amount more than the ones I've compared it with. That being said, and this was a mistake on my part, these setups I compared are on RWD sedans and all AWD setups I have since seen run about +30 and a 9.5 width wheel at most. Do the AWD sedans have a wider track width than the RWD or am I missing something? Pictures attached are what the fitment looked like

 

The RWD and the AWD are the same, but you just had a front diff and transfer case. The reason it pokes out so much is that the AWD is raised higher than the RWD. So the only solution is to lower it on coil overs or lowering springs to get the fitment right. For example, I have a coupe AWD and went with 19x8.5 +35, and with the stock set up my wheels would poke out in the front. After lowering it on Swift springs it has a perfect fitment.

 

Yup need coils to lower the car which will tuck the wheels better.

 

Oooof. I'm not familiar with the AWD height and camber gains from lowering but that looks like it'll take a lot of camber to fit 10.5 +22 under the rear fenders.

For reference here are my 9.5 +35 PF01 wheels on 275/40/18 tires with -1.4 degrees of camber and lowered 3/4 inch from the factory sport suspension:

 

It is very likely that from you research, you were missing teh alignment needed to fit that specific spec. 10.5" +22 is a common wheel many stanced G37 sedan run. most run a 255/40 tire with about -3 to -4 degress of camber. so a combination of stretch tires and negative camber.
