I don't see why anything that would fit the m-sport wouldn't fit the IS since I'm not aware of any brake/suspension changes. I could be wrong. My IS is scheduled to get here around turkey day time, so I have until then to figure this out.
Edit - went to TR and simply built a 17 inch winter tire/wheel package. Seemed straight forward enough -- what am I missing?
