Or, you could complicate the matter and do a narrow hub swap.

While I am tempted to get carried away, that is likely the route I'm going to take.
I remember reading somewhere that it may be possible to get the e-brake on a 128i to work with 135i rotors if you swap the e-brake backing plates with ones from a 135i and use the shoes from an e46 m3. I may take some measurements to see if there's any truth to that. But since the hubs need pulled to swap the backing plates anyways it's probably just going to be easier do the axles and knuckles.
Do you know if there are any differences in the knuckles themselves between 128i and 135i or is the difference just in the hubs?
