The most common cause is uneven pad transfer to the rotors causing rotor judder which is a pulsing that feels a lot like warped rotors. Assuming the rotors were installed properly you *may be able to resolve this by carefully re-bedding the pads to get a nice even pad transfer and allowing them to cool very gradually overnight. If that does not work, having the rotors turned and then pads bedded should do the trick.

We do a lot of track work and if we end a session quickly and park the car with hot rotors, uneven pad transfer is likely and makes the weekend less enjoyable. It has happened a few times over the last 15 years, always my fault for stopping the car hot. Re-bedding the pads and gentle cool down worked 2/3 times. In the worst case the rotors were a gooey mess and I just replaced them and started over.
