Can you point me to the place online, i'm in Georgia. I prefer to buy them outright instead of exchange. Did you exchange or buy yours, by the way....your car is HOTTTTT and i like that you keeping it close to stock and not adding some ugly rims, lowering it and all that foolishness. CLEAN Ride and it's still classy, good look man.
You can get them on ebay, if in so cal, you can get them from OEM wheels in santa ana. They are a chrome exhcange place, and you can get them in stock finish. They wont fit your car without spacers though due to the larger calipers on the gs430 versus the gs300
