Porsche PCCB (Porsche Ceramic Composite Brakes) is a very nice system.

You can pick that up for about $8000-10,000 I do believe. As an option from Porsche I think that it is sub $10,000. Granted, it used to be about $12,000, but the price has since reduced. I didn't opt for them for a few reasons. However, they are a good system.
