Again, my hope is that this information proves to be useful in the future for someone considering the purchase of a CTT with PCCBs on it.

If you could sell the left over PCCB brakes to someone else to offset the cost of the TPC brakes, great other than the swap being a PITA. Otherwise, PCCBs on a Cayenne seem like a horrible idea unless you've got ridiculous amounts of disposable cash.
