Buyer of my Z wanted better price minus the C-2's. These wheels are no longer made. All have 5x114.3 bolt pattern and are silver with polished lip. Specifics are:
front - 18x8.5 (28 offset) with Dunlop Sport 9000 235/40 -18's rear - 18x9.5 (45 offset) with Dunlop Sport 9000 275/35-18's
Tires and wheels have less than 3000 total miles and have no blemishes, scratches, nicks, curb rash, etc.
The following link will show them on the car. Let me know and will mail you specific pictures off the car, closeups, etc.
