I did a visual side by side between an E55 front rotor and an E63 one. They seem to be a match. The retail cost is $1000, but I think I can get them for $800 each at my delaer. I am an inch from trying them out.

The rears are a different story. The E55 rears have the parking brake on the interior side of the hat, so that threw a wrench into things.

Does anyone know if the SL65 2 piece rear rotors may be an option?
