brand new F430 OE disks (4 of them) is about US $8000-10000, depending on where you buy it. I can hardly image 4 pads and lines are 32k USD.
The way it looks is the bulk of the costs is in the rotors. Were you to put these on a street car you would never have to replace them due to the materials and manufacturing process. And it also appears that were you to ever get a chip on the rotor it is machineable where OEM are not and the rotor could be saved. They appear to be marketed twards the racing and tracking crowd.
