UPDATE:

Here is another option that I just tested. You CAN fit 355mm or larger Stoptech Z4M (yes, the M/S54) front kit on the 3.0si. Here is what you do:

- Purchase 6061-T6 spacers 12mmID x 28mmOD x 14.28mm long
- Purchase longer M12x1,5 bolts (I found M12x1,5x50 flywheel bolts part number 11222243051)
- The trick is to install the caliper bracket BACKWARDS (just flip the bracket). You will then bolt in from the front of the spindle, sandwhiching the 14.28mm spacers between the bracket and the spindle

And that's it. Install the rotor, slide on the caliper, perfect fitment. I'll have some photos soon to demonstrate.

Now you have two options: 355mm Stoptech (or 380 if you wish for Z4m), or 335 caliper+brass guides/z4m rotor swap. Both I feel are great track setups.

Yes, I jumped ship to the Stoptechs. The main reason? My favorite PFC08 pads are very hard to find for the 335i calipers.
