3 sets of rims in one year, eh? Impressive.

These look good. Like they belong there. Not sure how you would classify them... tri-split 5-spokes? Certainly knuckle-busters keeping them clean and waxed. Anyway, with these on your car, no one is going to see your non-sport brakes, which I suspect is part of the appeal.

Didn't know you were going to do this. All stealthy like, Sean.

The 18s sit flush without the use of any spacers? I somehow doubt that.

mjnoles1

Wait? Are you saying the 18s and 19s is the same amount of flush?

If some people could give me some feedback? I thought people were getting spacers, so it sits flush like the 18s? Am I mistaken, are the 18s and 19s the same amount of flush WITHOUT spacers on both sizes?

Thanks. This way I never have to rotate my tires.

Exactly what I was thinking. Infiniti calls them a 15 spoke. I prefer to think of them as a baroque 5-spoke.

Yes. That's certainly part of the appeal. If I do get a BBK, I'll have to go with something that stands out so people know I spent a stupid amount of money for no reason.

Who knows? The phantom modifier might strike again.

It all comes down to offset, the OEM 18 & 19 G37 Sedan & coupe wheels all have similar offsets in the +43 to +50 range, the Convertibles have offsets in the +30s. The biggy is the 7.5 front staggered 18s, they have a +43 offset and are an inch narrower than the rear 8.5+50, which will net about 5mm more sunken in than the back wheels.
Here's all the OEM 17 through 19s (except the verts)

So, if I see something like this: "19"x8.5". Cast aluminum. Made for Nissan/Infiniti by Enkei. Weight: 26.5 lbs. Bolt pattern 114.3 x 5 Offset +43"

The "Offset +43" that is what I need to eye to see if it is suken in or if it is the same as the OEM xs? Wheels? To have the same effect of the stock and the 19" I need to match the offset of the 19" to the same offset of the stock XS? Is this what it means?

Offset is the main part but width has something to do with it as well. The stock sport sedan 18s have a width of 7.5 and offset of 45 (I'm pretty sure, at least mine were). The stock sport coupe 19s have a width of 8.5 and offset of 43, so even though the offset is only a 2mm difference, the wheel itself is 1 inch wider which means it sticks out more.

That genuinely made me LOL.

I have my old wheels from my coupe G35 2006 19"-8 and 19''-8.5 with 30 offset and I am planning to put them on my new 2013 G37 Journey that has 17" so is that possible and what size spacers will I need?

Those wheels wouldn't happen to be those beautiful forged Rays would they?

If I've gathered anything from the wheels and fitment postings, it's that one needs to put the things on and tweak them once you know what's up. There's a lot of variables. Even if people have a Journey like yours and put on the same wheels, they can look totally different from one another.

Offset is the amount in mm that the wheel mount flange is "offset" from the wheels center point. A +30 offset means that where the wheel mounts to the hub is 30mm closer to the outside of the wheel. If you increase positive offset this brings the mount further out which in turn makes the wheel sink further into the wheel well, so a +45 will sink in 15mm further than a +30.
Hope this makes sense. And a wider wheel w/ the same offset will extend out 1/2 the increase in width, so a 1" wider rim will extend out 1/2" if the offset is the same.
Here's a good calculator for trying various wheel/tire setups

Sorry, should have been a bit clearer~it comes down to offset if the wheels are the same width. A 1" wider wheel w/ the same offset will extend out 13mm (and extend in 13mm as well).
The stock Sport sedan wheels have staggered 7.5 front 8.5" rear rims, but the AWD Sport sedan wheels are all 18x7.5

Here's a great wheel/tire link (it's a four page list but page 4 is very helpful)

I'd love to know the answer to this as well. I'm trying to do the exact same thing. I've been reading these forums for hours trying to find out. Also I would love to see a g37 sedan that is not lowered on 19 inch rays if anybody has a photo. Thank you all!

Anyone have spacers on just the front wheels? I'm thinking 5-10mm (tops), would be great to see pics

Totally fine with how the rear wheels look/fit, but the fronts are sunken in a bit, so visually it gives off the effect that the front wheels are a darker color than the rears (guess because the fender hangs over the fronts more):


Extra pic for giggles...

STownSaint, that is the 19" coupe with out spacers? That does not look sunken in at all, to me at least.

"blnewt" or others. If I put 19" coupe wheels on my XS, will that change the geometry of the vehicle and how Infiniti intended the XS to drive (other than 18" vs 19")?

I ask, as I am sure Infiniti, like all car manufactures, put in a lot of thought of the exact wheels to put on the XS. The exact inches, diameter and offset. If I change that, then will the suspension, etc work and move different than intended by Infiniti (other than the 18" vs 19" difference)?
