So I got a deal on some 370z 19s and have decided to go that route with my G37s instead of keep the factory 18s on there. I know that I have to get the spacers for the front wheels, but I had a couple other questions.

1. Will I need spacers for the rears as well? If so, what size?
2. Car is not lowered just yet and I'm still on the fence about doing that so I'm wondering if anyone could tell me what is the best tire sizes to go with 19x9 (fronts) 19x10 (rears)?


On another note, I have a Brand New Set of Bridgestone Potenza RE050A that I bought from Tire Rack and was planning on putting on my G37s 225/50/18 and 245/45/18 that I no longer need because of the upgrade rims. So if anyone is interested PM about them. I paid a little under $1000 shipped for them and I'm looking to get close to that for them.

 

Z 19s fit the coupes real well but a bit aggressive for the sedan, without a drop the rears will poke out of the fenderwells, even w/ a mild drop they'll probably poke a bit. About the widest tires you can run without problems would probably be a 275/35/19, the fronts will be OK w/ 245/40/19s. If you drop it pretty deep you could run 285s w/ some excess camber.

 

So unless I drop the car those rims are almost pointless to put on the vehicle? Btw I was check out the fogs on your 09, info please?

 

As you can see the rear offset is real aggressive, even at that zero-gap drop they're right on the edge. If you keep the stock height they'll be out about a 1/2" or possibly more.
As far as the fogs, here's my DIY link
