There was a TSB for the SRT to replace the stock rotors with slotted rotors but only if the car had less than 12k miles on it. you can find it
here.
If you meet the requirements I would take it in and have it done as the members that have it seem to be happy. I missed out on it and will need to buy my one at some point.
I'm not surprised that someone might be on their 3rd set but that's because they most likely do a lot of road racing where you break hard and often.
