The stockers are actually pretty sexy on that car/color, and they're not dinky wheels - they're 8.5's stock. I'd go with some Enkei NT03's in a big fitment if you wanna go nuts, but not sure how much you want to touch the fenders.
If you want some 17's for winter, I still have your Sparco NT-R's that I'd give back to ya - they're jsut sitting in a corner of the garage.
