I've contacted numerous dealerships (both German and American) and they all say I need the 34206797600, per VIN. However, a few retailers claim I want the 34206797598 because my car came with the base brakes. Then there are others that say I need the 34206797600 due to the xDrive's larger hubs.

Any help is appreciated.
What is the build date of the car? There is a cut off where all cars have large hubs. Or, pull your rotor and take a pic I can tell you.

See the attached photo. This is my method of figuring out whether a car came from the factory with the smaller 160mm diameter rear emergency brake that fits inside the smaller rotor hat, or whether the car came with the larger 185mm emergency brakes that only fit under the larger rotor hat.
