I just bought cadmium plated zimmerman cross drilled rotors for my MY97 from an ebay seller with this web site:
www.gforcebrakes.com
Cadmium plating is supposed to inhibit rust on the hats and outside edges of the rotors.
Others here have bought whatever they liked (aftermarket-wise) and masked off the rotors and sprayed the hats with high temp silver or gray paint and then mounted them.
