Those are mazda 6 rims. The 6 replaced the 626 (which never came with 17" rims) in 2003. The info I found for these rims is 17x7, 60mm offset. Stock ms3 is 18x7 with a 52mm offset (this is what I found searching, somebody please correct me if I'm wrong). I don't know if the difference in offset is enough to cause problems or not.
