Matt -- the wide-five zero offset Empi rotors are roughly $170 each, or less than $700 for all four corners, including a pair of rear axle nut spacers if you need them. You would need barely more than the mechanical skills to change a tire in order to replace the rotors. You would need a monkey-big long-handle breaker bar and socket to remove the rear wheel nut, and re-torque the nut onto the new rotor.
BUT, I don't know if the Empi rotors are a compatible fit with your existing calipers and mounts. It might not be so simple as merely swapping rotors; or, maybe it is. I just don't know.
