Don't forget improper tightening of lug nuts-

A quick way to warp your rotors is to over tighten or unevenly tighten the lug nuts. The wheels are a lightweight material that absorbs and then dissipates heat. They are bolted to a hard and dense steel hub that conducts heat.

Not evenly torque to the lug nuts causes the rotors to twist and wave when cooling after heating from braking.
