Anyone know is 17" wheels will fit on a 370Z?

Do 17s even matter that much for Hoosiers? My R7 in a 295 are 429/tire and the 315/35/17 are a shorter gearing still for a 395/tire cost. The 295/35/17 are 376/tire though. The 315/30/19 are 507/tire so I do see the benefit of 100/tire there...

My 295 are 2.35% shorter than stock gearing and with how much more grip the Hoosiers afford, the extra gearing is pretty needed. I can't imagine going to anything shorter.

The 315 or 295 in a 17 are 3.5% and 5.77% shorter. If you run a 295/315 stagger in 19s you're looking at 1872 vs 1542 before "membership" discounts. So that's 330/set difference so at two sets per year and throwing in comparable 17" wheels it's about 3 years to break even. The question part for me is how will performance be impacted by the shorter gearing and higher tire pressure? Does it justify the money saved? If I were strictly comparing 295 vs 295 the 212$/set and 5 years to break even just wouldn't be worth it. If you're burning 10 sets of tires per year though, my estimations would be extremely off base .

Sidenote, if you plan to run wets, you're going to 18s or 17s for sure, and most likely in a 275 square setup, in which case it's a 96$/set difference and that's extremely hard to justify scrounging around for a 17 that might fit.
