Simple question about square wheel setup and offset
If I run square wheels what size spacer will I need in the rear to bring the to match the front? Is it 10mm? I may be stating this incorrectly.
I know if I but a square setup on the car the rear wheel will look like it's pushed into the car relative to the front wheel. How big of spacer in the rear to fix that issue?
Oh and I'm not looking for "Hella flush bro". I just want to retain stock F/R track ratio. Thanks

Example, my car, 9.5 +15 square wheels, staggered tires. No F&R clearance differences other than the larger rear tires that "even out the fit".

Was looking at set 18x9.5 +24. Also another set 18x9.5 +18.
So going square doesn't change the ratio from stock at all if you maintain the same offset front and rear?
I come from mostly BMWs and one camaro. Both of those had the rear wheel set in further if you went square. I guess nissan engineers know what we plan to do with their cars from the get go

For me, I had a set of wheels and tires that were what I consider the "perfect fit" for both performance and looks (happened to be 9.5/10.5 +22 with rolled fenders). I now use that setup in the tire calculator to determine how close I can get to that same "perfect" on any new wheels/tires I'm considering by playing with the offsets and from that, knowing exactly what size spacer I would need, if any.
Both of the sizes you mentioned will work very well as is, no spacers.... unless you want to get the tires to kiss the guards. The room in a Z's fenders were designed to fit the staggered wheels and tires but conveniently a square setup works just fine.

With a 255/265 tire setup, you can mount 9.5" wheels with a 15 mm offset, front and rear. That will give you the slight stagger you mention, and it will work with TCS and VDC. The slight stagger will give you a little less under-steer, but still makes handling predictable (safe). Also be aware that sway bars (different models and different settings) will affect under/over-steer.
