It'll poke a little but tuck just fine, what wheels are you considering? BTW, Tein doesn't make any coilovers for AWD Gs

FWIW offsets at +40 is perfect on a 9.5 running 255/40 FWIW, check Zahy Matars build thread.

 

Thanks for the speedy reply blnewt, I was looking at the ferrada fr4s or the gramlights 57DR not too sure on what yet couldn’t find any pics of others having it on a g37 sedan. Any suggestions on wheels?

 

Rays Gramlights are nice, the 57DR only runs up to an 18" though, I've got 18s on my sedan and am glad I went that route. They have them in an 18x9.5 +38 which is the same size I'm running, but I'm on 245/45 front 285/40 rear, could run 255s no problem in front though w/ plenty of brake clearance, mine are Wedssport SA10R.
The Gramlight 57xtreme is up to a 19 though. Here's a good link for cross shopping some higher quality wheels, most are Japan sourced and lighter weight.

So 18s over 19s, Can I run 255s all around? With 18x9.5 +38 or would you recommend a similar tire setup like yours? I would I need any additional parts?? I got lost on the forum when you guys started mentioning hubs and camber stuff. Also what are you lowered on?

 

Here's my G when I was running 245/45/18s all around~

As you can see there's room to go to a 255/45 all around, and that's what I'd recommend (vs. the 245s) if you want to go w/ a square setup. I'm lowered on Megan Street LP coilovers set to 26.25" from the ground to the fender arcs, virtually zero gap at the fenders.

The Infiniti hub bore is 66.1mm, most aftermarket wheels have oversized bores so they can fit a large # of vehicles. What you want to achieve is a tight fit at the hub so you use adapter rings to get that exact fit.This will eliminate or drastically reduce high speed vibration that can happen if the rings aren't used.

18s are typically lighter and the tires are cheaper, so that's one nice advantage, also the slightly taller sidewall (to achieve the same rolling diameter) will give a slightly softer ride.

 

Thank you for taking your time out to explain that to me, I appreciate it,

I’ll be going 18s with the recommended tire sizes!!

 

I have this exact setup size wise on my RWD G sedan on Tein Basis Zs. In the back it's perfect but up front it pokes. If I could do it over I would have got 8.5s and spaced to taste. Another thing is 255 on 9.5 looks slightly stretched while on 8.5 it looks more square shouldered. I prefer the square shoulder look. Finally you also have to consider camber. If you are lowered I would definitely consider a kit. That will affect fitment as well.

jlow this is thread is for square setups (i.e. same size wheels and tires front/rear)

 

I'll move them to the Vossen thread

 

225/50-18 simply isn't enough rubber for the G37xS sedan, can I get away with running 19x8.5 wheels (45mm offset) with 255/40-19 tires on all 4 corners with factory suspension height? The overall circumference of this setup is within 0.64% of factory, so I'm more concerned about clearance. Thanks!

I've also considered 18x8.5 wheels (45mm offset) with 255/45-18 tires . . . I care more about having more tire than aesthetics.

 

Hi Bionicman,

I have a 2011 XS Sedan, and I'm running 19x8.5 +35 w/ 265/40/19 on all 4, no issues. It is one size higher than manufacturer recommended for the rim width but works with no issues. Factory height, might lower on coils or swift next season (newt will that clear btw? I want to have camber/toe within spec.)

 

That sounds promising, but the 35mm offset is giving you an extra 10mm of clearance on the inside over the 19x8.5 +45 wheel I had in mind . . . I'm not sure how critical that difference is. I need to turn my wheel full lock to pull into my driveway, so rubbing up front would be a real issue.

Are the factory 18x7.5 duck feet wheels on the G37xS 45mm offset? I thought I read that somewhere.

 

I think unless anyone was running obscenely wide rims, the tire is where rub would occur, correct? And with a 10mm wider tire but 10mm further out, my tire would be about 5mm further from the inside. I can't say for certain but it definitely looks like I have enough room up there lock to lock.

I do believe the factory wheels are 18x7.5 +43mm.

 

That should be fine, 19x8.5 +45 is not very aggressive and you shouldn’t run into any clearance issues inside or out. For reference, I’m running 19x9.5 +35 on all four corners.
