May be a good time to do so, but would prefer to stay with the stock brakes if they are adequate and won't require rotor replacement as frequent as the dealer is sugesting.
If that is the case, I would just get some pads and call it the day. This might be blasphemy to mention this but I would check to see if Auto Zone have some pads (prob not) that are lifetime guaranteed. Abuse those pads with free replacements until you upgrade to StopTechs.

Usually, you would turn the rotors so that would create a flat surface. Can you do that on drilled rotor or slotted rotors?
