Project Infiniti G37S: Advan RZII Wheels & Nitto Invo Tires

by Aaron LaBeau

When we first bought Project G37S there weren’t a whole lot of choices while looking for an extremely specific trim package like our Sport. Out of the two cars available locally, we rolled the dice on the higher mileage example at a savings of $7k. Unfortunately, part of the compromise, in addition to more wear and tear, was that the wheels were chromed. Yes, people still chrome wheels; a sales manager had them chromed, and someone looked at said wheels and thought, “I’ll take it”. We did too which makes us hypocritical, but there’s no way we were going to keep them for long. It’s with a lot of anticipation that we tackle the wheel and tire upgrade.

Unboxing our new wheels was quite an event, complete with fabric covers. Perhaps the only better unboxing is a new high def TV.

Advan calls this finish hyper black, but it’s a multi stage color that changes depending on the available light and viewing angle. We thought the color would work well with our car, exposing the high-end factory brake calipers and buck the trend of black wheels.

It all starts with internet research, right? Lots and lots of internet research. Self professed experts on web forums. Sooo much misinformation, so much opinion, so much BS. But every now and then you find a gem, and that’s what makes all that research time worth it, right? The G37 forum is where we found the lead on the Fast Intentions G37 exhaust, and it was where we hoped to find some decent information on wheels’ sizes.

19×9 inch front wheel shown. While is this a cast wheel, Advan used the latest techniques for strength in analysis simulations to produce a cast wheel that is both light and strong.

Side cuts are made along the spokes of the wheel to reduce weight without loosing strength.

The front wheel size for our G37 Sedan was easy to figure out; 19 x 9 with an aggressive 35 offset would push the wheel right to the fender. No messing around there. Rears were much more difficult to narrow down. The first choice was whether to run a square setup (all 4 wheels/tires are the same size) or to keep the staggered setup that the S model comes with. We kept the staggered setup with the idea of wider tires in the front for better cornering and wider tires in the rear to help put the power down. The rear wheels proved to be much more difficult. Keeping with the same 35 offset as the front, Advan offered a 19 x 10 inch wheel that would stretch a 275/35/19 inch tire just enough for performance. We referred to the MotoIQ Proper Tire Selection in making this decision. There was another confirmed G37 sedan found on the G37 forum that had used a similar setup. The pictures found on the forum seemed to tell the story that 19 x 10 inch 35 offset would work, but mounting the wheel and tire setup to the car told a different story.  Even with -1.5 degrees of camber, the tire poked out past the rear fender.

So close, but it just didn’t work. This was with -1.5 degrees camber, any more would drastically reduce the life of already quick wearing, high performance tires.
