On the other side of the coin (not a debate, mind you, just another opinion), I've had my car for almost two years now. I bought it with 109K miles. It now has almost 153K. It had OE rotors and pads when I got it (no telling how much wear at that point). I had to replace the front pads (with OE) shortly after I bought it, so, you'd think there was considerable time on the rotors). In the, approximately, 50K miles I've put on the car, I've not experienced warped rotors. I've had the occassional hard stops, and God knows they certainly had the chance to warp while heading down the mountains in Snowshoe and in the Smokies. Of course, I feel safe in saying this, since there is not a meet any time soon and I would be in danger of brakes going out and taking 24 days to have them replaced . . . just in time to drive to the meet.
So, all in all, despite the paranoia I had caught from others' brake stories, I'm more than satisfied (through my experiences) with the OE equipment. Albiet, I may be hearing one of my bearings "singing." Trouble is, I can't tell which one. Guess I'll have to wait for it to get worse -- it's a mere hum at this point.
