I've started the shopping list to continue my BBK upgrade project. The fronts are complete and I want to match with a fancy set of rears.

The common route seems to be 996 rear calipers, some custom brackets, with (I think E46 M3) rear discs, but not sure yet on that, I'm still researching.

Does anyone have parts stitting around they want to part with ?

I'm getting ready to do my brakes. For thr rear I have 135i calipers, 1st gen X3 or E46 rear backing plates and your choice of 1st gen X3 rear rotors

Please let me know how you get on. I'm still investigating options but would rather copy/paste a proven solution that someone else has experienced all the pain with, first.

This has already been done by multiple people. I have the 135i brakes both front and rear, the fronts use the M Coupe/E46 M rotors

What discs do you use on the rear for this? You mentioned first gen X3 but do these work with the z4 handbrake? And what brackets? Seems a good conversion to me!
