@tholyoak - I'm sorry, normally I wouldn't pursue an arguement. And I don't mean to belittle or diminish your mechanical abilities in the least. I've read many of your posts and they contain valuable information, I don't think there's any question about your skill level. But in this case, you're simply wrong.
It's not a matter of what one believes, this is fact. I too have been repairing and maintaining cars of all sorts for 20 years and then some, incl. porsches, so I can assure you there was no misunderstanding of what my Tire shop told me.
The reason I'm persisting is that this is one problem which is easy to avoid, but has expensive consequences if the procedure's not done correctly ($800+ for a set of rotors). I don't want readers to get the impression that this is a matter of belief because it isn't.
Over torqueing of lug nuts and wheel bolts is a major cause of rotor warping. Full stop.
If you won't accept an article from AutoZone as proof, here are a dozen more that you can look over, and I hope, learn something new from.
