i bought the car in november 2000 and im fairly sure it still had the stock rotors on it. i drove on those until this march and never experienced any warping. my driving has not changed at all, so unless these rotors noticeably
increase heat, i shouldn't be experiencing any problems.
also the torque specs im talking about are not for the lugnuts, which are 80 ft.lbs, you were right about that. im talking about the rotor-hub bolts. maybe thats specific to only a few cars, as on my model Accord because the front rotors are inseparable.
let me quote somebody...
"What advantages do drilled and slotted rotors have? The most notable is they have an increased surface area to allow better cooling. Other advantages include lower rotational mass, better off-gassing properties, and increased wet performance. Do they run cooler? Yes! Based on the average of several controlled data samples these rotors run on average 82º cooler in the front and 27º cooler in the rear. The downside to drilled and slotted rotors, other than cost, is they are more prone to warp if not torqued correctly. They can also make a slight whirling noise during hard breaking."
i now notice that it says "increased surface area", which doesn't apply to me, but that is only one of the listed advantages.
here is the URL of that review in case anyone is interested.

im not arguing with anyone, im just trying to figure out what exactly happened and what i can do about it. so if you think its my fault, please tell me
