I wore the left frt pad out on my CSS at COTA back in May. I was going to change pads over the 4th of July (been driving my LE since COTA) and I figured I should have the frt rotors trued up before putting pads on. The guy at O'Reilly's calls me back and says 1 of my rotors is warped. Picked it up and sure enough, the left rotor was very warped. I had driven 3 day at COTA and warped it sometime during my track time and drove 1000 mi back to OMA and never felt any shudder while braking. I was surprised but it defn needed replacing. So you could have warped rotors and not know it.

Bought a nice set of Bosch zinc rotors for $80 ea at O'Reilly's.
