Warped brake rotors are probably the single most improperly diagnosed problems on any car today.
I regularly track my car and speak with other drivers and I have never met anyone who “warped” their rotors.
I have experienced terrible vibrations both on and off the track and it has never been the result of “warped” rotors. Usually, it is improper brake in or just crappy pads. Unless you have an actual imbalance in your wheel and brake set up (entirely possible) then you have uneven pad transfer.
