I noticed that the Stoptech Kit 83.148.4600 shows up for both the Z4 3.0si and E46 330ci. Wanting to make sure this was correct, I looked up the OEM part numbers and sure enough the calipers are the same part numbers. Rotors are same size but have diff part numbers.

E86 Z4 3.0si:

E46 330ci:

So with that said, does that mean any BBK (Stoptech, Brembo, etc.) for the e46 330ci should work on my Z4?
