Gee Crazy Fool, mine and others have lasted over 100K and have driven in rally,race, and high speed driver's ed situations - where do you get your info (disintegrate? Never seen that) and how about the part numbers for the great ones you've added and the new stopping distances you have achieved. How about dust? I;ve tired over a dozen pads and they all dust so bad and offer little if any better performance. Bet you still have your stock rubber lines....
