How do you tell the stock wheel on the 03's from a replica. I am pretty sure I got mine with the replicas but I can't remember because I haven't driven the car in about a year. What points should I measure from to tell the size (tire on and wheel mounted). The answer may be completley obvious but I just want to make sure before I purchase new tires that they will fit. Trying to go with 315's out back (Not the nittos).
