I assume you already have good pads and fluid. If not Ford Heavy Duty DOT 3 is really good for the price... but you have to change it out frequently. EBC Red Stuff pads are also very good for the track. I am not sure you can get a set of Red Stuff pads or not....
Since you already have the SVT brakes with larger rotors I would think you shouldn't have too many heat related brake problems once you change the fluid and pads.
I saw you mention ducting in another thread. I would highly recomend it. It may not be the easiest thing to do but moving air over the calipers and rotors will help out a bunch.
