Thanks for taking the time, jchammond. I'm new to both the 370Z (we bought our Z in the spring) and the science / jargon of staggered tires, spacers, etc., so please forgive me for my ignorance and treat me like a 5-year-old when it comes to this subject.

I think you are saying how to make imaginary lines drawn through the outer edges of a Z that has 4 rear wheels installed on it as parallel as possible, correct? That is, if rears are installed on the front, their outer edge is going to poke out more than the rears do. And in order to make the rears poke out that same distance, the rear 19", 275mm-wide OEM Rays wheels need a 25 or 20mm spacer, correct?

You pretty much lost me here.

FWIW, our vehicle now has about 10,200 km (6,338 miles). AFAIK the camber on all wheels is as it came from the factory, whatever that is.

You say "19x10+30 front". So this is if rears are put on the front (as I suggested in my original post). What does the "+30" mean -- that the edge of the wheel will "poke out" 30mm from where they normally are (as if a 30mm spacer were installed on the OEM front wheel)?

The OEM rear, still on the rear, having the 25mm spacer installed, will be "+5". What does that "+5" mean?

Then you suggest that a 20mm spacer instead of the 25mm "may be closer", but I'm not sure closer to what -- being flush with the fender -- the edge of the rear wheel being "even" (on the same straight line) with the edge of the front?

I'd be very interested to see what a rear looks like on the front without actually having to manage that with our vehicle. If all of the above is done as you suggest, do all of the wheels poke out from the wheel wells? Do you happen to have a photo of a Z that has the rear OEM sport wheel and tire on the front?

It's beginning to sound to me like the way to go is with 4 fronts instead of 4 rears. What do you think of that option as opposed to 4 rears?

Thanks again.
