I know it can be a litttle confusing, here is a great post to reference in the top 100 FAQ, it even lists your sizing:

Q: What wheel sizes and offsets do I need?
A: Generally speaking, there are a LOT of different combinations that people are running on their Z or G.
Let's get the basics out of the way first: You need a lug pattern of 5x114.3, width between 8 and 11 inches, and diameter of 17", 18", 19", or 20".
Here are some of the more popular wheel and tire sizes (for good reason) that people put on their Z's. There is no "RIGHT" answer but there is a limit to how big or small you can go.
18" combination:
Front 18" x 8.5" , Offset +15 to +25, Tires 245/40/18
Rear 18" x 9.5" , Offset +15 to +25, Tires 275/40/18
(lower offset such as +10 in rear is possible but may require rolling)
Front 18" x 9.5" , Offset +25 to +30, Tires 255/40/18
Rear 18" x 10.5" , Offset +28 to +35, Tires 285/40/18 or 295/35/18
(lower offset such as +23 in the rear is possible but may require rolling)
19" combination:
Front 19" x 8.5" , Offset +15 to +25, Tires 245/35/19
Rear 19" x 9.5" , Offset +15 to +25, Tires 275/35/19
(lower offset such as +10 in rear is possible but may require rolling)
Front 19" x 9.5" , Offset +25 to +30, Tires 255/35/19 or 265/35/19
Rear 19" x 10.5" , Offset +23 to +32, Tires 285/35/19 or 295/35/19
(lower offset such as +23 or wider tires in the rear is possible but may require rolling)
From this, you get the idea of what is required to go with smaller wheels like 17's, (typically lighter, faster acceleration), or bigger wheels like 20's (bigger, heavier, usually makes you feel slower).
Get to know how to use the following tools and you will be able to figure out for yourself the correct offsets and tire sizes you need:

Wheel Offset Calculator
Certain combinations of LOW OFFSET and/or WIDE WHEELS will require what is known as "fender rolling" or "fender cutting".
If you are not familiar with the term "fender rolling", here is a quick but useful lesson you can learn in a couple of minutes: Go outside to wherever your Z is parked. Run your fingers along the inside edge of a REAR fender just above your tires. You will feel a sharp edge and a flap of metal sticking inward towards the car. Now, go up to the FRONT fender, and feel the inside of the fender again. You should notice that the flap of metal has been "rolled" upwards on the front fenders. This is exactly what fender rolling is all about. The rear fenders will need to be rolled to make room for wide wheels or low offsets, or else your tires may rub on the metal when you take hard corners or hit bumps. Any experienced wheel/tire shop should know how to roll a fender. If you go to a shop that does not seem like they know what they're doing, get out of there.

What offset to run on 19" wheel???
Hello, im kinda new to the z scene.. Always wanted one and finally got one. Anyways, wanting to run a set of dpe spr10s in a 19 and like a 10.5 rear and 9.5 front. I want an aggressive stance. Car is lowered with tanabe nf210s. Wanting wheels to be like flush with the fenders, if i have to roll them then i will, stretched tires???? Throwing that idea around too. Just want a really aggressive stance. Really wanting to know what offset to run with these wheels.. Ive searched everywhere and cant seem to find a direct response.. +12?? +20?? Input greatly appreciated...

I looked on that thread a few times and either people don't put their offset or are running different sizes than what I'm looking for.. I'm not being lazy just wanting some personal experience with these sizes so I don't shoot my money down the drain!

If you want to see how aggressive you can go you can also refer to this thread as well:

I would spend some time in both threads since you're new to the forum

Fitment Questions.....
Ok so I bought some wheels this past weekend. The specs are 19x8.5 +15 front and 19x11 +18 for the rear. I haven't bought tires yet ( have to pay off the wheels first) but I have been looking/shopping. I'm assuming for the front a 245/35/19. The rear I was thinking a 275/35/19 or a 285/35/19. Will I have to roll my fenders with either or both of these tire choices? The place I bought them from told me they are designed for 350Z's...hopefully theses will fit with no problems. Any input is appreciated.
fenders will need to be rolled. fronts are already rolled from the factory. i would go 285 on the rear so that it doesnt look stretched compared to the meaty front. you will also need a spacer in the front to get flush.
So with either rear tire I would have to roll? I would still need a spacer in the front even with a +15 offset? What size spacer?
the offset would be about perfect if the width of the wheel was 9.5" instead of 8.5." probably a 15mm spacer. and with the 11" wide wheel in the rear you need to go ahead and plan on rolling them no matter what.
