The best G37 wheel fitment (coupe & sedan)

Everyone knows you’re pullin’ up to the meet when they hear that ear-piercing, headache-inducing, straight pipe’d VQ. In this guide, we’ll show you how to add some class back to your G37 with a properly fitting set of aftermarket wheels… It’s an Infiniti after all.

Researching wheels for this platform can be a little overwhelming. You’ll see wheel diameters from 17-20”, widths up to 12J, and offsets from +50 to ultra-hotboy-specs like -30. Where do you even begin? In this guide we’ll cover a bit of everything, OEM+ fitment, stance, even some builds on air suspension. You’ll learn all the wheel & tire specs so you can order with confidence.

This fitment guide is all about the G37, coupes and sedans, 2007-2015 model years. Yes, it’s very similar to the older G35 or 350z/370z, but we figured it’s about time it gets its own guide. Plus, we already covered the Z.

Coupe vs sedan fitment

This is a big one, especially considering we’re lumping both into one fitment guide. The coupe is about 13mm wider in the front and 25mm in the rear (yes, a whole inch). To compensate, factory wheel specs are quite different:

So, the Sedan is a bit thinner, but both can take very aggressive aftermarket wheels. Also, both are plagued by very sunken ‘OEM’ fitment. But wait…. You might be wondering ‘What if I put those slightly more aggressive coupe wheels on a sedan?’. We got you covered:

Here’s a good look at the fit. These are OEM 19” coupe Sport wheels, no spacers. The general consensus is that the rear will be near-flush depending on the alignment, and the front will still be a little sunken, but much better than factory sedan wheels.

If you really want flush fitment from OE wheels, you’ll need to space them out. A 15mm front spacer can do the trick if you’re happy with the rear fitment, otherwise, a 5-10mm spacer in the rear can make it truly flush.

As we said, the coupe is 13mm wider in the front and 25mm in the rear. As a rule of thumb, if you're a sedan owner and see a coupe you like, you can copy the fitment by adding the respective +13 / +25 to the offset; if you’re a coupe owner, just subtract those numbers.

Recommended specs for aftermarket wheels

You didn’t come here to learn about stock wheels, did you? Here’s a quick look at the preferred sizes for aftermarket wheels.

19” is the most popular diameter, however anything from 18-20” will work great on this platform.

As far as width, 9-10” is a good range for a daily driver or weekend warrior build. However, these cars can go very wide… like super wide, especially coupes. You’ll see them running a staggered setup with rears as wide as 12”- that’s on factory fender arches.

Again, offset will vary depending on which chassis you have and what type of look you’re going for. For flush fitment on a sedan, aim for something in the +30-45 range, with a higher offset in the rear if you choose a staggered setup. The wider rear fenders on the coupe are a good match for staggered wheels. Most coupes run 20-35 in the front, and 25-40 in the rear.

Akebono brake clearance

The sport model of the coupe comes with an Akebono brake package, and the fronts are hefty. Whether you have one of these, or you put Akebonos on your sedan, you’re probably aware of caliper clearance issues. Nothing is worse than trying to mount some new wheels just to have them hit the caliper. Fronts cause most of the issues, rears are pretty forgiving.

To have adequate caliper-to-barrel clearance you’ll need at least 18” wheels. However, not all 18s fit, and caliper-to-spoke (or caliper-to-face) is yet another concern. Sure, a spacer solves this, but who wants to add spacers when they carefully selected the perfect specs?

Before ordering, there are some resources to reduce your anxiety. Here’s a list of popular wheels that either pass or fail. This doesn’t include everything. If the wheels you’re eyeing don’t appear on this list you could try searching forums, or if you have access to the wheels, you could cut out this template to check clearance.

Staggered wheels on ‘X models’?

Turns out this term isn’t only used in Tinder profiles, Nissan/Infiniti also dubbed the AWD version ‘G37 x’ or ‘G37xS’. Can AWD G’s use a staggered setup? Sure, as long as the rolling diameter is within 2% difference front to rear - the G37xS uses a staggered setup from the factory. In other words, make sure the overall diameter is almost identical. It’s all in the tire sizing, we’ll look at examples later.

Examples of G37 coupe & sedan fitment

19” wheels on a G37

Starting with the most popular, 19’s. With this size, if your car has Akebonos you won’t need to worry about caliper-to-barrel clearance.

This ‘09 G37x sedan is sitting on a squared set of TSW Nurburgring wheels. You don’t have to run a square configuration on an AWD car, but having everything perfectly symmetrical makes it foolproof. As we’ll see square setups are more common on sedans given they don’t have those wide ass rear fenders.

With these specs, 19x9 +32, the outer edge of the rim is almost perfectly flush with the fenders. This is with stock suspension. A quick note about lowering: if this same car was lowered it might be slightly tucked due to the ‘natural camber’ gained - but nothing that can’t be adjusted with alignment.

---

Now we see a sport coupe on 19’s. This is a staggered setup using a 9.5 front and 10.5 rear. Even with a 10.5 wide rear, there are no issues with rubbing or scrubbing. The offsets are going to be more aggressive as well: +30 front & rear. If you wanted similar fitment for your sedan you could increase these a bit: say +40 front and +45 rear.

This car will have tons of grip in the rear. The tires were sized up to match the wheels - Sumitomo HTR Z5 were used: 255/40 front and 275/35 rear.

Just because they’re a bit thin doesn’t mean they can’t party. This sedan is running Work Wheels, spec’d at 19x10.5 +23, all around. This shows just how wide you can go with this platform. This is well beyond flush fitment and entering into stance territory. Making it fit required stretched tires, camber, rolled fenders, and other trickery. Still, there’s a slight amount of poke, but it still looks good with the stretched tires.

As you can probably tell, this car is built for form rather than function. Not to say it’s all show and no go, but the stretched tires and camber indicate it’s built for weekend car meets instead of hardcore track driving. This car has slight rubbing when cruising on the street, that’s only going to be amplified if it were used on track.

If you’re looking to build a show stopper, you could try to replicate the look of this 2008 G-coupe on bags. But be warned, this type of fitment takes some serious work. First, this car is on an air suspension kit from Air Lift Performance. We can see a lot of negative camber. To dial in the suspension you’ll need camber arms, toe arms, traction arms… all the arms. In addition, the fenders needed to be rolled and pulled to give space for the wheels.

With the air suspension, this car has no rubbing or scrubbing issues when it’s aired up.

A lot of people (in the States) sleep on Weds Wheels , but in Japan, they’re some of the most popular. We did a whole feature on the brand - learn about an OG JDM wheel brand that might be flying under your radar.

18” wheels on a G37

After 19’s, 18’s and 20’s are about equal in terms of popularity. Both options look good on these cars, however the motivations to pick one or the other could be completely different. First, we’ll see how 18’s look.

If you’re looking for the lightest of the light, this set of 18x8.5 TE37’s are about as light as you can get. At +38 offset they are more aggressive than stock, but not by too much. The wheels still sit pretty far in the fenders. With 8.5J wheels, we’d like to see a slightly lower offset, maybe around +30. A setup like this would be best for a daily.

As we can see, these 18” TE’s clear the Akebono brakes with no spacers. If you’re looking for something timeless and super light, TE37 wheels are the way.

You could also choose 18’s if you wanted to absolutely slam your ride. In this case, we see a 2010 coupe on bags from Air Lift Performance. Compared with 19’s or 20’s, 18’s will be level with the fender when aired out. If you plan to run bags and don’t like the tucked look, 18’s might be the best choice.

Of course, you’ll need all the other fixings to go with the air kit, including camber arms, rolled fenders, etc. Air suspension ain’t cheap. However, these wheel specs could also be used on any other type of suspension, and at any ride height.

20” wheels on a G37

Finally, we finish things off with some dubs on the G. If you come from older JDM stuff like S-chassis, AE-Corollas, or etc, 20’s might sound like blasphemy. Thing is, they actually fit the G and Z34 platforms pretty well.

If you really like that tucked look, 20’s are a good option. Sure, it’s possible to tuck 19’s, but this 2008 sport coupe is doing it… while static. That’s right, it's on coilovers. We saw cars that were slammed on bags, but this mad lad is slammed 24/7. The wheel specs are pretty modest which makes them tuck nicely in the fender rather than having fender-to-lip fitment; ultimately, it’s personal preference.

You can find this car, and hundreds of others, in our Fitment Gallery. Check out more pics and details such as this car supposedly having zero rubbing or scrubbing issues… we’re gonna call BS on that. Unless you have 100k spring rates, this kind of static fitment will almost always rub on something.

Here’s a more measured approach to running 20’s. This 2012 Sedan is on Eibach lowering springs instead of airbags. His wheel specs are 20x9 +22 front and 20x10.5 +40 rear. This is perfectly flush fitment on a sedan. This car is also running a 275/30 rear tire, which is a bit wider than we’ve seen previously - some fender rolling was needed to make it fit.

These ESR wheels clear Akebonos with 2-3mm to spare. If you’re looking for a set of 20’s, these run about $360-370 per wheel - not bad considering the large size.

Wrap up

Infiniti G-sedan and G-coupe fitment isn’t as difficult as it may seem. The important takeaway from this article is to base your wheel specs on the correct chassis. If you have a sedan, don’t order coupe specs and expect them to be a 1-to-1 fit. Remember the 13 and 25mm difference front and rear, respectively.

Generally, these cars can handle wide wheels and tires. We saw everything from 8.5 wide to 10.5 wide fronts. As long as you get something between 18-20” diameter, and don’t put a ‘-’ instead of a ‘+’ on the offset, you should be good.
