^ well, as explained, it does not only occurs during track use...
a heavy car like this on n' off the freeway and even around town in stop n' go, light to light can warp with a heavy brake foot.
when they get hot is the time this happens and no matter how much slotting we add, if you lay onto the brakes too hard/at the wrong time, no rotor can avoid it.

what I'm trying to cover here is the experience you chose to list, is not specific to our company/product. it has no relation to the quality of AR, rather the nature of the part itself. it's something that can happen to ANY brand rotor.
reading your reply, infers it was an issue or defect of the rotor we sold you and I'm clarifying it's not whatsoever...brand XYZ would have done the same thing.

its a common misconception that a warped rotor is the rotor's fault, so I want to clear the air and correct anyone false expectations or assumptions.
