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

Irrelevant grouping of questions WITHOUT knowing the wheel spec. Generally speaking though, if you run conservative square sizes, say a 9.5" wide wheel, the offset F&R will be the same. Tire choice will also be a factor in the fit. So, what are you thinking in terms of sizes?

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

Well, if you think about it, the stock Z wheels 8/8.5 had similar offsets (within 3mm). Even the double stagger Nismo with 18x9/19x10 had the same +30mm offset F&R. So, reasoning that through to aftermarket wheels, why shouldn't the offsets be pretty close to the same? Sure, there comes the time when you want to maximize the stance/track width by running different offsets - even when running same widths (square). That's where the tire calculator comes in handy.

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.

That makes sense. I guess I was mislead by some of the threads I read. Thanks for the help.

I don't think it was asked, but will you be running the stock tire ratios or equivalent, or are you looking to run square so you can rotate tires? Just double checking.

I was either going to run square 255s or 265s. Or, I was going to run a slight stagger of 255/265

Just make sure you don't have TCS or VDC because it won't be happy.

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.

There is no perfect answer to this question, equal offset and width front and rear will normally require a 10 tp 15mm spacer in the rear for a matching look
