Well, Racing Brake gave me a link to a set of front and rear rotors (pads optional):

Price is right around $2000, which I'm ok with. Unfortunately, they also informed me that the hats are backordered right now with at least a 2-3 week lead time
Emailed Fontana to see if they have the fronts in stock. I can wait on the rears.
