As for car up on jacks, wheels off and running up to 80mph without any road/load factor I don't have the means to do that. But I could have the rear end checked out. That thought did pass my mind. The only reason why I'm thinking that it has to do with the AP kit is because like I mentioned earlier, this vibration issue started the day I installed the kit and been the same pretty much with two different AP discs but I know this BBK is one of the best selling out there so I'm very puzzled, as are the guys helping me out from Stilen and AP. I've even tried swopping my front wheels with a 6 series and a co-workes '11 E92 M3 with ZCP 19" wheels. My wheels did not vibrate on the other car(s) and the vibration was the same on mine so I can pretty much rule out the front wheels at this point.

So it sounds like it's pretty much down to the brake disc being the culprit then. Hope you get them sorted eventually. Do let us know when you find out what exactly is wrong with them.
