I dont think this is an issue. If this is my original post has a link to a Z4 forum where someone has a part number for a long Bolt

130i handbrake shoes are large diameter. 125i brake shoes are small diameter. So they don't work.
The solution is one of 3 choices - I will edit here later to explain ( enlarged 125i 128i brake shoes, custom fit 130i/135i brake shoes with welded piece, e46 m3brake shoes)



BMW perf calipers is what you referred as BBK above?
If so all you need is
2x 130i Hub
2x new 125i rear bearing cuz it will be damaged on install.
Handbrake solution

OR if you want new rear rotors, it is just this:
2x 135i rear rotors
Handbrake solution

both solutions will have you bend back/ cut the rear dust shield a bit

Yes Performance BMW bbk

thanks for the info
