Yea the moron who wanted the rotors to last designed it. If the rotors practically fell off when you took the caliper off, like most, they would warp alot faster. If Ford and Dodge used the same design you wouldn't be so familiar with changing them. The original rotors in my 95 Accord weren't changed until almost 300,000 miles and I'm very hard on breaks. My dads 98 Cavalier, his are warped by 20,000 miles every time and he is not hard on breaks. Our cars weigh about the same and our breaks are very similar in size. The better design is what makes my rotors last.
