Time to replace the origional brakes on my zanardi. I want to stay with the factory calipers, yet I also want to improve the braking performance as I hope to track the car soon. I think I will go with the Carbotech Panther +, but I haven't decided on brake rotors. I would like to go to a slotted disk. Delphi/Lockheed HTSL heat treated disks from SoS look like a good choice, but they are very expensive, as are all the slotted disks that Dali sells. I'm having a hard time spending $800 just on disks which I think of as a wear maintenance item. Is there really any improvement using these expensive slotted rotors vs. the oem rotors, or using cheaper oem style aftermarket rotors? Thanks much
