wait, so would 18x7.5 and 18x8 sport wheels from the X fit these without spacers? seems to me that the x7.5 up front is a bit small

 

The G37S sedan wheels fit w/o spacers
G35S sedan wheels need spacers.

 

so that excludes the G37xS wheels, right? they are thinner up front and in the rear

 

correct

 

but wait just a minute, Infiniti.com states that the S RWD package includes 18x7.5 front wheels, which i assume are the same as on the X all around. So if that 18x7.5 wheel fits the larger Akebono's up front, why wouldn't the same x7.5 wheel fit the 2 pot setup in the back?

Unless the 18x7.5 wheels on the S RWD have a slightly more aggressive offset, which i doubt.
But if that's the case, a 10mm spacer would do the trick

what do you think?

 

IIRC the G37X S doesn't come with the Akebono.
