We replaced the wheels on my wife's 2014 Z. The wheels themselves only have about 4500 miles on them. As you can tell from the pictures, they are in pretty good condition (only one has any "rash" on it).
We are located in the Twin Cities (Minnesota), so local pickup is of course preferred. However, we will ship them anywhere in the US if you cover the cost of shipping.
2 Fronts - 19x9
2 Rears - 19x10
I also have all of the chrome bolts that come with the set
Btw, I apologize for them being dirty, I took the picture as they were coming off the car at the shop
