offsets depend on wheel width.
what sizes are you considering?

I'm in on this, too. &nbsp;I'd like to run 17x8 in front and 17x9 in rear. &nbsp;I'd like to find out what the stock offset is, so I can determine the offset of the new wheels. &nbsp;I'd like to have the offset in the back just right so the wheels are even with the fenders, not recessed like they are stock. &nbsp;Know what I mean?

stock offset is I think +40mm or so. may be more with if you have the steelies and hubcaps.
Stock size, I believe, is 15x6.
I'll be putting on a pair of 15x7+5 wheels in the near future, which I hear fit fine unless you have a brake upgrade, in which case you may need a 5mm spacer depending on the brakes. This setup SHOULD clear z32 brakes, though I'm not sure why they didn't clear the guy who I bought them off's brakes. (I don't remember what his brake upgrade was-- def. not stock, nor was it z32... I think it was Project-Mu or sth like that.)

Luke, if you want 17x9 to fit flush out back, I imagine you should try for something like +35 or possibly +40 to prevent you from shredding your tires on the inside of the fender.

Big brake fitment is as much about spoke design as it is about offset. &nbsp;Some of the stock 7 spoke alloys will clear the 26mm Z brakes. &nbsp;Some won't without a small spacer. &nbsp;The difference is in the spoke reinforcements. &nbsp;In general a lower offset (+30mm) will aid in clearing the brakes, though a wheel with a deep dish or thick spoke design may not.

I think the number you need to know is backspacing.
