But the 335i rotor has a different offset from 128i. I now look back and see why others have not used the 335i rears.

Honestly, I have no idea why its working on his 328i, unless RealOEM is wrong and the 328i actually has a 335i carrier. 128i and 328i have different rotor part numbers, yet both are 300x20mm. Maybe the offsets are, in fact, different, but the 328i matches the 335i?

In any case, my only option at this point (at least to be able to leave tomorrow for the track), is to go with 328i rear calipers. I'm going to pick them up this afternoon and give that a try, along with coding the Performance Brakes into the DSC, if my other friend can help. Knowing I'm moving the brake bias forward, but that's not necessarily a bad thing (for limit braking) if the ABS is able to be retuned to accommodate it.

Any advice on rear brake fitment is appreciated!

Yep the hub is the other part of the equation.

The 328i rear caliper piston is 42 mm and will shift your bias to the rear which helps if you've installed the E82 6 pistons, E90 335i single pistons, or F30 4 piston.
