If everything checks out, scuff up the rotors and pads slightly, go get the directions for bedding pads off Stoptech's website and go do it again yourself. If all of that solves your problem, fantastic. If not, you've just eliminated another variable.
Something is wrong with your specific car. Few people have had rotor issues, and those that had them solved it when they went to aftermarket pads and rotors. You've changed out pretty much everything but the calipers, master cylinder and ABS unit, and the problem still occurs. This suggests to me that the root cause is not a braking issue, and the warping of the rotors are a symptom of something else being wrong. That makes me think something gets out of line when the nose dives under braking. You've claimed that the rotors were previously toasted in a single stop. That's not normal at all.

**** car. Done with it. I'm not going to go and bother blowing a whole day to do what Nissan should have done, unless Nissan is going to pay me my standard working hourly rate to do it for them. I work to pay for my toys, and while installing mods is fun and I like it, fixing things that shouldn't need fixing that shouldn't be wrong is just drudgery to me.
The nose doesn't have to dip. If the pads touch rotor, the car starts shaking, now. Previously it was just the wheel, but we are now to the point that I get a bit of that blurry vision when my head touches the headrest and I brake, sometimes. Maybe that sounds worse than it is, but the whole car is shaking and my Dad in the passenger seat who can tool around in a busted down ex police car with no AC and a floor-pan that you can see pavement through, immediately proclaimed "something isn't right".
Everything that you have listed was done by the dealership. They checked the calipers and everything. The service manager suspected some form of hardware issue and made sure it was all inspected. I KNOW they are going to get tired of seeing my car, so I don't think they limp-dicked it, I really don't.
Now you're right, I might come in and find something wrong behind them, but I'm not going to hunt around my Dad's warehouse to find all the tools I would need, and kill an afternoon doing it, when I am pretty sure it's nothing I'm going to detect without specialized items (tq wrench, maybe Nissan specific measuring devices?). I'm really just not keen on spending the money to buy a good tq wrench and burning an afternoon. Further, I sleep during the day, typically, and this isn't something you do at night.
I never loved this car, and I'm not going to go out of my way for it now of all times. I spent my time wrenching under it when the Berk CBE I bought wouldn't fit for **** and I had to off-set it enough that when it sags down and the hanger on the left side slips off the grommet, it's sitting level. That was enough fun for me. Oh, I also installed Z1 smooth intake tubing...without removing the strut brace. At night. With a flashlight. Without breaking anything. It became a struggle of ego.
