Im looking to buy a set of work vs-xx. They are 19x10.5+2 in the front and 19x11.5+5 in the rear. He currently has 245/35 on the front and 275/35 on the rear. I am at stock ride height at the moment but plan on lower with coilovers. How big of a tire can I fit front and rear? I dont plan on going super low, just enough to get rid of the ugly wheel gap.

You will need to roll the fenders with that setup. You can run wider tires but will need to pull the fenders and/or run camber.

Id like as little camber as possible. What is a better offset for me to look for in those sizes?

From the my350Z 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".

MicEdit 03-12-15: Should be noted that there are a lot of NON-hub centric wheels out there. If you can, try and find wheels that have the proper 66.1mm hub bore. However, if the wheels you are buying are only available in larger hub sizes, e.g., 73mm, you will definitely need hub centric rings to fill the gap and center the wheels on the Z's smaller hubs. I personally don't like idea of running said rings (possibly introducing another POF - point-of-failure) - but they do work and are better than not having them!

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 <====MicEdit 03-12-15: Get under the car and take measurements. Then use this to see what the effects are from various widths and offsets. It's not absolute but gives a good idea of what to expect when using various combinations.

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.

I am running my alignment with in the factory specs with no issues

but my sizes are more conservative than your 1st mention of what you want to run

19 x 9.5 O - disk (+17 - 3mm spacer = +14 ) 225-35-19 97 mm standard lip

19 x 11 O - disk +10 245-35-19 122 mm standard lip

I did not have to roll or pull anything
I am easily within factory alignment spec

lowered about 2" F & R coilovers

I do have SPL parts

Front / Upper Control arms , front tie rod ends , endlinks

Rear / Camber Links, endlinks , traction links

solid diff bushings

Hotchkis sway bars F & R

hope this helps

they are sweet wheels i would go step lip if i did it again
