I believe the rotors are the same. You can double check by comparing part numbers in a FastLane search. As a rule you should always replace both rotors (or calipers, pads, etc.) at the same time. Do yourself a favor when you replace the rear rotors and smear a light coat of antisieze compound between the new rotor and the hub. It makes life MUCH easier the next time around.
