^ I have the G35 sport coupe 19"s (Rays) - came off an 04... tapered holes for lug nut.
For your lugs, maybe get them powder coated black.? I did that to my lug nuts on my M35 sport wheels...

Thank you!
Can I get a sanity check on my offset math? I'm looking to go to Coupe wheels on my '11 XS sedan, and I'm trying to plan appropriately.
Going from the 18x7.5 XS duckfeet with an offset of +43
to a square set of 19x9 coupe rears with an offset of +45
By my math the wheel is 38.1mm wider, so half of that is 19.05mm. That's how much more wheel there is on either side of the attachment point. So if I'm concerned with the position of the outer surface, I would take that 19.05mm MINUS the difference between the two wheel offsets, right? (because +43 is further OUT than +45) If so, I end up at a total shift of 17.05mm further OUT than the original wheels.
If I'm currently running 15mm spacers, it would seem I could just remove them and be 2.05mm further out than I am right now. Does that make sense?
The issue that gives me pause is that I've gathered from reading this thread that the +30 offset vert wheels sit just about perfectly flush on lowered sedans. (I'm on swift springs) If the 19" coupe wheels have a +15 difference in offset from the vert wheels, shouldn't I need my 15mm spacers to make up the difference? I feel like I'm missing something.
Edit: the width offset calculator verifies I'd extend the outer position by 17.05mm. (I wish I had seen that before I did the math, lol) Maybe I was just misunderstanding the vert wheel application. It also says I lose 21.05mm of inner clearance, though. I'm guessing that's okay since a bunch of other people have done 4x 19x9, but I don't think I would want to push the wheels much further out.
