Then we'll have to disagree - on a LOT of points. My own experience is almost the total opposite of yours. And I'm not known for being either slow or easy on the equipment.
I have never cracked the OEM rotors at the racetrack. However, I personally have cracked several non-OEM rotors at the racetrack using both OEM and non-OEM pads.
I have never "melted" pad material an any of the roughly ten different kinds of brake pad I have used, and bedded in properly. Pad material can build up deposits on rotor surfaces, particularly if they are not bedded in properly, but you are mistaken if you think that pads "melt" onto the rotors. You might want to check out this web page from Stoptech's website to learn some of the dynamics of brake pad performance when heated on a racetrack.
I've run Motul brake fluid on the stock system for almost all of the 8,469 actual track miles I've put on my NSX, and I have never boiled the brake fluid.
I've run the last 1,000 actual track miles on my NSX using the Yokohama A032R track tire, which I would call a "like tire", and I have never boiled my brake fluid using those tires, either.
Then it's quite possible that no car's brake system is enough - for you and the way you are using your car on the track.
I consider myself one of the more severe cases in terms of usage, and the stock NSX brake system is very, very good, even for me.
I am not claiming that the NSX brake system is immune to problems from heat at the race track. Yes, you can run into problems with pad deposits on the rotors. Yes, you can run into problems with rotors eventually developing cracks. However, these are problems that can arise with any brake system. In fact, I have discussed brake problems with some of my NSX buddies who have put big brake kits on their NSXs for track use, and many of them run into the exact same problems with the aftermarket systems as with the stock brakes.
Like Ed, I have come to the conclusion that the stock brakes are perfectly capable for track use, and are similar in performance to many of the aftermarket systems used by some who disagree. Given that your experience is so drastically different from mine using very similar setups, Edo, I can only conclude that the causes of the problems you have had lie not with the equipment, but with the techniques of the driver.
