If I detect any rust on the rotor area on those cars,and they all have it. I soak the hub area with PB blaster and spray some into the lug holes for good measure, let it sit for a couple minutes, then start whacking it with a Big hammer until it pops off. (I place the blows near the hub where the lug holes are).
I usually get it within three good whacks.
It helps to turn the steering wheel to the best angle to swing at the rotor with your hammer.

I then clean the hub area with a wire brush and put a very ,very light coat of anti seize on the hub where the rotor rusts to the hub so the next one will fall right off when the time comes.

I then put a rag into each lug bolt hole and wipe out any blaster that may be on the lug hole threads.
