Have the new rotors machined. You probably installed the less expensive Chinese rotors. There's nothing wrong with them except they were "aged" on your car. Cast iron parts made in the U.S. are set outside for 90 days before the final machining is done. Any warping takes place before that final step. The Chinese don't age their parts first; they just cast them, machine them, and send them on their way. Once machined after they warp, the problem is not likely to occur again.
If it does happen again, chalk it up to do-it-yourselfer-itis. It is extremely important that the lug nuts be tightened to specifications with a torque wrench. 95 ft/lbs is common for most Chrysler front wheel drive vehicles, but double-check for your car. If you don't use a torque wrench, you can expect warped rotors again in the future.
