Anyone know what I can do to help my car stop better? Or at the least, prevent the HORRID brake fade that I get from even ONE slow down from 150.

I get this everytime I goto the track, after a run I have almost no brakes. The car stops VERY quickly, but less then 3 seconds after I begin pressing the brakes, they fade, and I have to push VERY hard to slow down the rest of the way. Can I upgrade the pads to something better? Or do I have to go with slotted/drilled rotors, 4 pot calipers, etc... someone?
