Hi just a quick question before I possibly run stagger setup on my G37x sedan. Has anyone had any transfer case or AWD/VDC issues from running a staggered setup for long term?

I'm aware as long as the setup is done properly there should be know issues with the VDC acting up, but what I'm wondering is if anyone had any long term issues with the transfer case, AWD sensors etc...

Thanks any input is appreciated.

I do know there's been issues reported at speeds over 75mph if your front to rear diameter is off by more than 1%. There were quite a few that ran staggered when the 3% variance was recommended and had to get closer matched tires. I don't like to recommend any combos that are over 0.6%, especially where the rear tire is smaller than the front since the variance will increase since the rears wear faster. With the selection of tire sizes out there you can get near zero in 18s & 20s and 0.5% w/ 19s so if you do decide to run staggered that's what I would shoot for.

It would be nice to hear from some that have ran 50k or more miles on those setups for further confirmation, I know they're out there

I've put about 10k on my staggered set-up, and that includes a couple track days. I have 245/40s in the front and 275/35s in the rear on a 19" 370 wheels. I've been rough on my tires which are Michelin Super Sports and I need to get me a new set soon as I've killed the inner edge from too much camber my first tracking. It's not 50k but I've eaten through about 3~4/10s of tread and never had any issues. High speeds have yielded no issues as of yet. All that said I have not written off that it may become a problem.

Great feedback!! Thanks!

I'm itching to get some Z wheels as well. A couple of ???, please.

Did you have to run wicked camber to get the rears to fit? Are these Z wheels the 9" and 10" variety?

Thanks a lot,
Sean

I will see if I can grab some pictures later on.

370z 40th Anniversary Edition Wheel (dark platinum... or whatever color it is)
Wheel Brand: Rays Engineering (OEM)
Wheel Bolt Pattern: 5x114.3
Wheel Size: 19x9 (front), 19x10 (rear)
Wheel Offset: +47 (front), +30 (rear)

I'm running a 20mm spacer up front, might mover to a 23mm spacer in the future depending on what I do with my front camber.

Front Camber: -1.1 left / -1.1 right
Rear Camber: -1.9 left / -1.9 right

When I first setup my suspension I went with a 3 inch drop to attempt to get the center of gravity down there. The required camber for the rear with that kind of drop was close to -3.5; which was just horrible. That coupled with the fact that my roll couple went to crap and driving daily on most bad roads was a nightmare with that kind of drop had me raise it to it's current height which is 26.125" in the rear (top of fender-well to ground). This allowed much more camber adjustment. I can go out to about -1.4 camber if I want now in the rear; which is ideal and within factory spec.

Bottom line: if you go with the 370z wheels and you do it right (i.e.: spend the money on the camber arms for the front and back and toe adjustments and you don't overly drop the car) you can get everything within factory spec.

Thanks I've just been curious about the long term effects of driving with staggered wheels on a AWD 37x because I seen many stagger setups but often wonder if people kept them, or was it to much of a hassle, or caused problems down the road on a 37x.

It would be good to have long term feedback, especially if there were certain tire combos that may have started out ok and caused issues as they wore down.
FWIW Here's the best tire combos I'd recommend for 18s/19s/20s, then pick proper wheel widths/offsets to get them to fit~
18s
235/45 & 265/40 (0.07%)
245/45 & 275/40 -0.07%
255/45 & 285/40 -0.22%

19s
225/45 & 255/40 0.06%
235/40 & 265/35 -0.37%
235/40 & 275/35 0.67%
245/40 & 275/35 -0.52%
245/40 & 285/35 0.51%

20s
235/35 & 275/30 0.07%
245/35 & 285/30 -0.07%

This calculator should be used when trying new setups~

Keep in mind the variances with a minus sign have smaller rear diameters, this isn't as good since the rears wear faster, this will cause the variance to increase over time. Not a big deal when you're starting at zero or close, but if you're already almost at 1% variance this needs to be considered. None of the above combos should have enough rear wear to be a issue but

I was wondering if 19s, 225/40 & 255/35 would also work?

I'd run 225/45 & 255/40, this will give you a 0.22% variance AND keep your overall diameters similar to your OEM diameters. The 40/35 series on those tires will be almost an inch shorter, I wouldn't recommend doing that.

Great thread. Been wondering the same thing as well.

Great post and very cool to see we have our own tire calc here!

Match outer diameter, match outer diameter, match outer diameter! The tire combinations recommended by blnewt are the golden key to running staggered tires on an AWD application with the most important factor being matching F + R outer diameters.

Staggered on AWD shouldn't always be feared - some OEM's even sell AWD cars with staggered wheels/tires. At the end of the day, though, there can be some inherent risks if one isn't careful, it's definitely something to look closely into before clicking the "Buy!" button.

I'm running 245/40/19 and 285/35/19 supersports on my x sedan with the coupe rims...put about 16-20 kms so far...no problems

Sounds like a nice setup, any pics you want to share?

I forgot I told someone I would post a fitment pic as well. Wheel and alignment spec here, or just scroll up. And now a quick and dirty lens flare picture to hide dirtiness of car:



Please excuse the very dirty car parked outside my even dirtier place of employment. Also in dirty car defense I would like to add it is tree bukkake season, and fighting the pollen is futile.
