I have three wheels from my 2003 WRX for sale, good condition with the original Bridgestone RE92's and about 15k miles on them. They were never rotated, so there's one from the front with a good amount of tread left and two from the rear that are down to the wear bars.
Good for a full-size spare if you're willing to give up ~2 inches of trunk depth -- this is why I am only selling three.
Asking $75 each, pick up in San Mateo or Palo Alto.
(edit: set of 4 no longer available. Individuals still available)
