I had a set of '98 NSX rims sitting around my house (16", 17")so I thought I would put them, on the 240 to see what they looked like. They look like crap, and that is with a 10mm spacer front and back to clear the coilovers. They may look ok with 4 rears. What's the verdict?

Then with the Ray's G35 19" wheels:
am running these with a 10mm spacer all around but they may have cleared the coilovers with out them. Z32 brakes would be no problem without a spacer. My fenders have a small roll on them just enough to flatten the fender lip front and rear.
