So, have you ever actually WARPED a rotor before?

IF you think you have, are you absolutely positive it was warped and you weren't just thinking it was because of some extra judder in your brake pedal which was REALLY from uneven brake pad deposits on your rotors?

Don't waste your money. No point in drilled/slotted rotors and if you are really bent on replacing them do not get anything but an OEM-or-better quality rotor.
