Hey all- I have an '02 IS300 and discovered that my right front wheel has a cracked rim. Any suggestions on the best place (i.e. cheapest) to find a replacement? Also, on a related note - my spare tire is shot and I have to replace it. Is there any chance that I can use the rim from the spare and put it on my right front, then find a full replacement spare? Or are they different sizes? I bought it used but as far as I know they're the original wheels. Thanks! Tommy
