But you won't be able to find something to fit the front. You need 18" wheels to clear those calipers, and even then a big offset is required so that the spokes don't hit the face of the caliper. If you really want a spacesaver, your best bet would be to get whatever the ST guys use and if you have a blowout on the front wheels you'd have to steal a wheel from the rear and then put the spare on the back. The only other option that I have seen people do on the RS is buy a full size wheel, put a crappy tire on it, and just leave it in the trunk. Not a good solution IMO, but I've also never felt the need for a spare tire and haven't missed them when they're gone.
