I would recommend that you continue to use OE parts for the brakes. When I serviced my brakes (f/r with new rotors, pads and hardware), I went Aftermarket on the rotors (Centric Power Slot - cryotreated) and pads (Hawk HPS). After 3 ~ 4 months of my typical agressive driving, the brake performance became pathetic. I went back to stock and all is good ... really good. Well sort of. Porsche Engineers finally figured it out that the brakes in the 2003/2004 CTT are undersized. Hence, the larger (380 mm and two piece) rotors in the Cayenne Turbo S in 2005. Maybe the additional 50 HP got their attention. Some day, I'm going to install the 380 mm or 410 mm upgrade.

If you still decide to go Aftermarket, check out Zeckhausen Racing for a price comparison ... http://store.zeckhausen.com/ I've had excellent service from these guys.

Does anyone have an old Brake ring from a Turbo S they want to give away? I'll pay shipping. I want to do a little comparative research as there are a lot of 380mm brake rings out there and I would imagine Porsche used some kind of standard ring. Some are better metallurgy than stock cast iron but some are equal for less price.
When you buy new Turbo S rotors do you get the rings & new bolts or do they sell you the complete rotor with hats and all?

Here is one that might work.

Here some more that Porterfield sells. Just need to check offsets and hat ring size. Really need that old rotor, the ones on my TTS are not ready to come off yet.
