Do you live near a self service yard? The local Pick Your Part has rotors listed at $14.99 with a $3 core charge. Probably $20 each out the door. On the 50% off sale day about $13 each. I know there aren't Pinto's every trip, but man, maybe I should be grabbing them when I can. If they Mic OK and aren't deeply grooved they are probably good. For the record I did get a spare set a number of years ago because people were complaining they were $100 each. Now $150!
Which brings up the subject..., can your rotors be turned? I think Pep Boys charged about $13 a rotor when I had my wife's Civic rotors turned. I opted to have them turned figuring the warping had run its cycle. I felt new rotors would just warp again. So far 9 months later everything is good.
