Exactly, CC and I've had this discussion before. Warped rotors are rare. What most people feel is either a hard spot or pad deposits.
I chech rotor runout quite a bit (with a dial) on the racecars. It just dosen't happen much.
We do spin the tires or move the car 6 inches 2 or 3 times when they come in after some hot laps, especially if we're doing tire temps and don't want the driver to slow down on the inlap. If the driver does a real cooldown lap, it's not necessary.
Sitting with the brake applied after a hot stop will cause a hard spot. Yes, technically that is what it is. I misspoke by calling it a warped rotor I guess. But, with the slotted rotors I haven't had that problem. Whether it is gas, heat or both that the slot is allowing to escape, my "warped rotor" or "hard spot" problems have been eliminated on all my vehicles that I've put slotted rotors on.
