I'd recommend that you look at going with an aftermarket rear rotor with a hat that sits over the hub. Cars that are going to sit often will pit the cast iron rotors and grow crusty rust that will kill the pads when you try to use them to clean it up.
The removable rotor, even for your application, is a really good serious consideration. Ditto on the front rotors as well.
They are just going to make like simpler for you.
