Ive done at least 5 different dsm brakes, and 4 or 5 brakes on Chrysler/ Mitsu Cars. Listen to XtremeRS.. Buy new rotors, they are only $20-25 a piece, and will save you $$ and time in the long run.
Few other tips for brakes: Never spray the rotors w/water after braking hard. Also, torque you're wheel bolts to the same torque setting, or close to them. Tightening one more than the others can cause warpage. I've messed up rotors in both situations. Hope this helps.
