Okay, so here are the facts I have so far...
This link is for a G37 Sport OEM 18" wheel that WILL fit with the BBK on a G37 (I know this because I have seen tons of factory G37 pics with the BBK and these wheels). They are 18X8 with a 43mm offset:

I didn't really like them so I wanted to get these instead which are also 18X8 with a 43mm offset (I have not however seen these wheels on a BBK G37 or M35/45 for that matter):

Does that mean that the second wheel will fit? Does anyone know of any other factory 18" wheels that will fit our cars with the BBK? I have some BRAND NEW Toyo Proxes 4's (245/45 R18) laying around that I would prefer to use versus buying new 19" tires for the winter...
