I've done a decent amount of work on my Mazda 3, and I'm looking to replicate that on the G37xS. I'm looking at the following wheel options that look like they'll fit with a squared setup from the research I've done and what I've found:

• RAYS Gram Lights 57XTREME:
  • Sunlight Silver
    • Size: 18x8.5, Offset: 42mm, Bolt: 5x114.3
  • Matte Graphite
    • Size: 18x7.5, Offset: 40mm, Bolt: 5x114.3
    • Size: 18x8.5, Offset: 33mm, Bolt: 5x114.3
    • Size: 19x8.5, Offset: 45mm, Bolt: 5x114.3

I'd rather stick with as close as stock as possible in terms of size & offset; however, I know that might not be the case for some options. Any opinions on what would be best fit from what I listed above? Also, I assume a 245/45-18 would work on the 18x8.5 wheels, 225/50-18 on the 18x7.5 wheels? What about the 19x8.5 wheels; would it be 245/45-19?

As for the Enkei Raijin wheels, I'll call them my backups. I sized them out on Tire Rack and was given the following:

• Enkei Raijin Gunmetal (Tuning Series):
  • Size:18x8, Offset: 45mm, Bolt: 5x114, Tire: 225/50-18

I'd figure I'd run into little issues with those, but my main questions are on the RAYS Gram Lights above.

Oh and of course, to complicate things, I'm looking at KSport Kontrol Pro coilovers with a very mild drop; however, I wouldn't want to get into that until I know what size wheels I'll be getting.

Thanks for the help in advance!

You could run up to a 9.5 +45 all around on the same 245s for a slight stretch but a bit more concavity in the rims.

When I mean mild drop, I mean no more than an inch. I was thinking around .75" drop up front and .5" in the rear. Maybe 1" in the front and .75" in the rear...just want to make sure I'm not "plowing snow" when it's that time of year.

Of the ones you listed the 8.5 +33 will give a nice fit at the fender, and again you could run a wider rim (up to a 9.5 +45) w/ those 245/45/18s.

For a mild drop Tanabe would be the mildest.

There's a lot of nice 18s on this site if you haven't seen some of them

They have aluminum adapter rings on ebay, just need to be sure of the diameter of your new wheels' rings and then adapt down to the Infiniti diameter of 66.1mm. Tirerack sells plastic ones that are OK but don't hold up well if you're doing a lot of wheel removals.

CNC Aluminum Bolt-On Wheel Spacers (20mm, 25mm, & 30mm)

Thanks!
