i am shopping for my 80 280zx and am wheel hunting.. my questiones are
how will off set effect the car?
right now im intersted in these rims that have +20 offset will this effect the stance?
please any advise on how - and + offset effect the car, particularly the bigger numbers, 15 to 40.

Before you do any wheel searching, you need to understand the difference between + and - offset...
First Google result:
what does positive offset mean versus negative offset in regards to wheels? - The Unofficial BMW M5 Messageboard (m5board.com)
So in a nut shell, if you put +20 offset wheels on the stock 280zx hubs, you will shove the wheel in more, not out more.

Zero Offset
The hub mounting surface is even with the centerline of the wheel.
Positive
The hub mounting surface is toward the front or wheel side of the wheel. Positive offset wheels are generally found on front wheel drive cars and newer rear drive cars.
Negative
The hub mounting surface is toward the back or brake side of the wheels centerline. "Deep dish" wheels are typically a negative offset.
If the offset of the wheel is not correct for the car, the handling can be adversely affected. When the width of the wheel changes, the offset also changes numerically. If the offset were to stay the same while you added width, the additional width would be split evenly between the inside and outside. For most cars, this won't work correctly. We have test fitted thousands of different vehicles for proper fitment. Our extensive database allows our sales staff to offer you the perfect fit for your vehicle.

I had an alignment done but as you know there is no adjust in the rear. Regardless even with the Tokico springs and the drop that follows the car was still in spec in the rear. You can slot the rear cross members if you need adjustment....

They are the exact same diameter as the stock wheels. 40 series is a good performance sidewall - I find the 60's on my 240Z are too much but since it's a full Nismo suspension it's about all that gives on it. I think 17s are perfect on the S130, 16s for the 240Z and 18s on the 300ZX. 19s look fine on the 350Z and 370Z.
You'll also have a hard time finding anything performance/size wise in anything smaller than a 17" now....

I really like the Rays - they make nice stuff but it's not cheap. What is the width of the wheel? Any pics of the actual wheel?
I didn't slot my rear cross member because it was still in spec. I may slot them if I go to coil overs...

ok so after a long search, tons of test fits and a bunch of idiots who dont know what a lug pattern is.. and my freinds constant nagging about how i can just buy a perfect fit.. i decided to go with some custom diamond rims
so yall guys shoot me some spec numbers ..
im thinking 7or 8 in the front and 8 0r 9 in the back and for sure gonna have a fat lip.. not sure about diameter yet but 15,16,17 maybe so include the tire diameter in your specs...
im also thinking aBOUT -20 offset inpart due to FricFrac clean fit..
i am for sure going through with the purchase after more research on what looks good and works with the z..(function as well as style)
thier rims are pretty affordable for custom, and im hoping my purchase will help more z's get that wide tire, dished lip we all deserve..."with-out mods"

because when you buy proper tires, you don't need to buy oversize ones that look like a bag of dicks.
I've already got 14s, just need to get them rebarreled and they will go on. going with 185/55's on these
yes, I have quite a few suspension mods.
this is when I wasn't rocking aero for a minute.
