Selling two pairs of 1" / 25mm wheel spacers: https://zcardepot.com/wheel-spacer-set-pair-1.html
I was gonna put these on my 280z but decided to go a different direction with wheels. They are 4x114.3 bolt pattern. As I found, they fit the rears fine, but the center bore is not large enough to fit the fronts. You will have to machine that out if you want to use them on the fronts. These are brand new with 0 miles on them.
If you want, I can include hubcentric ring adapters (73.1mm center bore to 66.1mm) with them.
Save yourself $20-$40 vs. buying online.
$50 OBO shipped per pair
or
$90 OBO shipped for both pairs
