I have a base '02 that I track a few times a year, and I would get fade with the stock pads, as well as the two or three different EBC compounds I tried. Finally I went with PFC 08 pads and I get no fade with them. But note that they dust pretty heavily and can be noisy on the street. They also require correct bedding in or they don't really work that well (all typical with track-oriented pads).
I'm unfamiliar with Hawk HT10's so it could well be your pads. Driving style can also contribute to brake fade as well. In other words, you might be slowing down too much for the turns!
I also use the Motul fluid and the ducts that 78F350 showed in his post. No doubt the least expensive Porsche performance part you can purchase!
