Thanks for posting your setup HankL. I recently bought a 370z and needed a set of winter wheels right away. Ended up going with the same setup you have, 18x8 F10 Sport Editions and same Blizzaks. Everything fit and looks pretty good for winter wheels!
Here's a couple pics if anyone else is curious or finds this thread later on researching like I did.
Sport brake clearance on front...pretty damn close, but it clears!
