I'm not to argue with you about it beyond this, but I have seen it and this article mentions it. It must come from uneven tightening and if you REALLY torque hard enough and it's uneven enough, you're going to warp the rotor. Read the article.

Either way, there's lots of bad things that come of under- or over-tightening and if you are inexperienced you can do some expensive damage. Even a cheap torque wrench will at least get you in the neighborhood. It's not an exact science, there's some leeway. I have a cheapo torque wrench (off Amazon) and when I do my wheels, it's plenty good enough. But when I went to do my header bolts (29 lb-ft IIRC) it was not up to the task and I had to go by feel.

So don't use impact guns or 6 foot pieces of pipe on your lug nuts. A person with a wheel wrench is NEVER going to tighten to the point of warping anything.

So... if you torqued then you should be good. Going back and retorqueing should not have any effect if you were properly torqued in the first place.
