In reply to:
Going to a larger rotor would be great, but also puts the car illegal for SSB or ITS, as do the drilled rotors.
It's all about class rules.
So I guess larger rotors are out of the question, if you want to stay in class.
Ducts are a good idea, as you know, but there are problems, as you also know.
Are your wheels of an open design that allows plenty of airflow to the rotor?
Is your brake fluid capable of handling the high temps of track use?
Pads... I was going to say EBC redstuff. Tirerack offers this pad for the early cars, and for SVT "after 5/98." When I plug in a 99 SVT, the Redstuff pad goes away. Aren't the later pads the same as the early pads, only on a larger rotor?
Anyway, there are other pad choices as well, such as Porterfield R4S, etc, and I think solid rotors will be your best bet for max heat sink.
Also, have you seen the article below? It may be helpful.
