I swapped out my Kia Stinger OEM 19" staggered wheels. These wheels have less than 2.5K miles on them and are in pristine condition. However one wheel has a small scratch (pictured), but will most likely be unnoticeable. In Myrtle Beach, SC, can meet w/in 100 miles ($600). Would rather not ship, but would probably be another aprox $200 to ship.
Not 100% sure if they will fit the optima, but reading one of the threads on this forum, it seems like it would.

Fronts: 8.0x19", 34 offset
Rear: 8.5x19", 46 offset
Bore: 67.1mm (same for Optima and Stinger)
Bolt pattern: 5x114.3mm (or 4.5") (same for Optima and Stinger)

So I asked a while back on here about putting on the 19...
And it was mentioned how off the offset was and that it probably would not work/be safe. Can this be confirmed one way or another since I saw this photo posted on a K5 facebook group. So what's the verdict, I would love to throw these badboys on my SX
