Yes. I was actually calling to schedule an appointment and this is what the mechanic told me. He said he would just inspect the thrust arm bushings and if they were fine put new rotors on... That's silly these are brand new OEM rotors and based on the tests I've done the thrust arm bushings are fine.
I know this isn't rocket science. I don't remember exactly but I am pretty darn sure I cleaned the surface underneath the rotors before putting them on. Also I would imagine that probably would have been a problem with the old rotors anyway.
As for not being seated properly, I looked very carefully at the rotors with the wheels off when turning both sides and they appear to be seated perfectly. Though I suppose it could be off by a little and imperceptable to the naked eye. Furthermore, please explain to me how 5 bolts torqued to 100 ft lb./ea would not ensure a perfect seating.
I guess I just don't get it. I don't mind taking it to the shop but i do mind taking it in the a$$, especially when i already HAVE brand new OEM parts and they just want to slap another set of new rotors on.
At least someone at brake job place can tell me if the stupid rotors are true or not. When you say dynamic wheel balance to you mean like a hunter machine you would use on a rim? I know a guy who owns a really nice wheel shop that would prob throw them on the machine for me. I suppose i could just throw the bitch back up on stands and put a brick on the gas pedal and watch for wobbling on all 4 corners too.
Last question. If the wheel always jerks to the right on the same stretch of road. Is it worthwhile to swap the rotors side to side and see if the jerk changes to the left???
Thanks for all your help again, you seem to be pretty knowledgeable about all these technical details. I am just getting antsy about getting everything fixed.

Not recommended.
No, because you can't likely show them to be defective.
If it is runout, you can measure it with a dial gauge. If it is out of balance, you can determine it with a dynamic wheel balance.
Yes, by turning them on a brake lathe. You are taking off so little that it isn't a worry.
No need to turn both, if you can isolate the problem.
Lots of questions. Have you considered taking it to a shop as recommended in your previous post which you reference above? You can spend a lot of time and money randomly replacing parts.
