To add some more info, I can conclusively say (and as already mentioned above) the 128 rotors do not fit as the rotor sits about 6mm too far inwards. If you still want to use the slightly larger rotor, you'll have to back mount the adapter pieces and get ~16mm spacers for them as well along with some shallow head hex bolts (interference with the caliper bracket).
I spoke with Simon (srs-concepts) about the issue and he concurs with the problem. See pictures for reference.
