is this guy lying about his offsets?

Offset: -20

Well depends on how low he is. I'm basiclly running the same stock nismos with 20mm all around which makes the front almost a 10.5 and the rear a 11.5 if your looking from hub out. We can fit up to a 13.5 I believe my buddy as 12's and there's a guy with 13's as well. So no I don't think he is.
I plan on doing 10.5-11.5 with 285 stretch n 325 rear.

Are nismo fenders wider than the non nismo z?

Nope

Wait...10.5 and 11.5 wide at those offsets and its not even super flush? Did they put the opposite sign on the offsets?

more like +10 +20, and even then that sounds wrong based on the pic.

Looks right to me?

rear should work, but iam more intrigued by how front can fit up to 10.5 width -10 offset

so what this is proving that the 10.5 with -16 will work in front? (well for obviously slammed and wheel sticking out set up.)

It all depends on the wheel design, backspacing, and the amount of camber that you use

That NISMO is running a set of SSR SP3's which have several disc sizes that you can select so your results will vary depending on the wheel and he's probably running more camber than OEM to compensate as well

definitely! I have a 10in rim in the front with a +22 and it sticks out 1/4 of an inch. His setup would stick out another 35mm more than mine.

I'm +25 on the front with a 9.5" and almost flush. My rears are at 10.5" +7 and I'm flush. Definitely not possible with those camber settings he has. His fenders arent rolled or pulled. To squeeze that, his camber would be much more noticeable. Plus his tires aren't even stretched.

Those are definately +10 and +20 NOT -10 and -20...
