Hello. I am a 2006 g35 coupe 6mt owner since april.
My car is fitted with summer tires, but with a realy cheap brand, accelera, but I had to replace front left with another brand, Nankang Ultra Sport NS-II.

anyways, I've been looking into some winter sets, and on craigslist, I came accross a normal 18 inch staggered setup for g35, and 2 17 set ups.

The first 17 inch setup is from a g35 sedan, and seems all the tires are the same size, 225/55/17.

The other set is from a 350z, but it only says 225/55/17, and not sure if its staggered set up.

MY question is, is it ok to have all same size wheels/tires, all 4 tires, for g35 coup?
and also, Im pretty sure my car is equipped with sport suspension package, would the 17 rim from 350z or g35 sedan fit my car?

Thank you in advance!
