Unofficial Enkei Wheels Thread
And to answer the offset question, lots of guys run +15 all around and it seems to be a pretty good balance of aggressiveness without being too much. May rub with wide tires in the rear though. My 285's on +15 wheels rubbed until I rolled the fenders. 275 or 265 and lower might work without a roll though.
18x9.5 +15 square is my set-up as well. You can go up to a 285/35/18 on the rear on a 1" drop and good springs with no issues as long as your rear fenders are rolled. On the front with the same drop you can go up to a 265/35/18 but it pokes past the fender a little. I found a 245/35/18 front and 275/35/18 to fit just right for my application and no TCS/VDC issues.
Issues going the 285 route in the back is that it would be a VERY beefy tire and you may lose some performance in the sidewall with it. It will also stick out past the fender by about an 1/8" up top.

Why not 18x10.5 +15 all around with 265/35 tires that way u can rotate your tires when needed.

This is all really good info, I appreciate it.
When you say "square" do you mean thats the set up on all 4's? Also when you say there may be some performance loss due to sidewall are you referring to turns or straight lines? As stated these would be for DD so "straight line" wouldnt be anything I would be concerned with. Now spirited turns getting onto the highway is a different story.
My guy I emailed said +15 is the closest he can find in 18x9.5 to +22 so I may have to go with that.
That thread is definitely very informative. With a 9.5 all the way around I can still rotate them just fine, cant I? Reason not going so wide (although very tempting) is these will just be DD wheels/tires, and I feel with a 9.5 I have the option of running a smaller tire to save me some cash when replacement time comes.

I have the 9.5x18, 10.5x18 with 265/35, 285/35 rpf1s with +15 all 4 and that is very nice. Rear fenders are rolled, lowered on Bilstein PSS10's. The +22 may want to be pushed out a bit because +15 is great offset.

Square is same size wheel size on a 4, yes.
As for the performance issues.... The wider you go from 275 means you have to beef up your sidewall to a 40 to maintain the aspect ratio properly on a 9.5" wheel, but if you are lowered that can become an issue because the extra height can cause rubbing. If you stay stock height you can easily go with a 285/40 in the rear and be fine.

You can also run 255/40 front and 275/40 rear with it no problem.
Yeah, I printed off CZP's fitment template, made it into a sturdy card board one and checked it out on a front wheel (off); plus called czp and Z1 to talk in person about the 18" enkei's fitting, they both said that "less than +25 should be fine" and the +15 turned out just right with good clearence on spokes and barrels; Fills the wheels out well! I was nervous until the install haha! Recommend the setup much.

Plenty of options in this Enkei thread OP for you refernce if you search for "rpf1 18x9.5"

I would try to go 18x9.5 (+15) all around and ensure that your rear fenders are rolled and you should be golden with 255-40-18 and 275-40-18 as others have suggested

Enkei RPF1s.
I have a all stock 350z pretty much and have been looking to get some rims. I did some searches on these rims and haven't seen any with this offset so I was wondering if these will fit my car and look good. They are
18x9.5 +45 and 18x8.5 +40 Enkei RPF1s.I can get them locally for $1000 from a buddy with tires. Thanks.

You typically want to stick with a wheel and tire that has something within this range (taken from the Top 100 FAQ)

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:
Tire size calculator (click)
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.
