I ended up buying used 335i wheel carriers and half shafts, new wheel bearings, brake shoes and ABS sensors. It was PITA but it works.
BTW: I’m using BMW performance rear discs part No. 34216795755

Oh. Didn't know that at all, thanks!! So the BMW Performance rotor turns out to be the same size as the 135i rear rotor. Since the front BMW Performance rotor turned out to be the same as the front 135i rotor it shoulda been obvious. D'Oh!
So if I want to find a floating rotor for use with the 135i rear caliper I need one that fits a 330i. Well, that was simple. You da man!
