same size 18s on all 4 w/sport package?

[steelertown]

I did some research and from what I understand, I can put 18s on a 370z with sport package if I understand right. My question is, well sort of a 2 parter. I would like to confirm that I could put 18s over the 2014 sport package without having to mod anything and for the part I am currently unclear on, can I put the same size 18s on all 4? Or would putting the same size on all 4s throw off the handling and make it unsafe? I don't track or race it I am asking for daily driver purposes and I just don't want to keep replacing 19s with how much they cost, but I don't want to do it if it compromises safety.

What size and offset would I be looking for? Sites like tirerack wont give you the option to search 18s for sport package.

18's are just fine for the 370 as long as the offset is low enough to clear the brake caliper. That's for all wheels though. The barrel of the wheel will clear the brakes.

As far as running a square set up (example: 18x9.5 all the way around) that can also be done with no problems. I'm not sure if the VDC will act up if you have the same size tires all around though. You may want to do some research on that.

This is a good place to start regarding 18's. You can see what works and what you like.

18's on a 370z

I have an Enkei PF01 18x10.5 square setup with 275/40-r18 Toyo R888s (I know, small tire for the width). This is on my 2011 sport package Z. +38 front +15 rear offset.
