According to stoptech it's nearly impossible to warp rotors, here's a technical paper from them about it.

If you don't see any cracks or other defects what you're experiencing is likely hot spotting, which is uneven pad deposits that cause them to grab harder at those points. According to stop tech it's usually caused by improper bedding.

I've had this happen before and have done exactly what the paper I linked suggests (for bedding rotors), and it completely eliminated it. Stop from 60 - 5 mph about 10 times total. Start with light braking the first time, the next time brake a bit harder and continually increase braking pressure each run until the 10th time you're slamming on the brakes to the point ABS kicks in. You could also try having the rotors turned down at a machine shop.
