Since we are about to confirm that 330i rotors work for 128i/125i
I found these
Performance Friction Direct Drive Two Piece Floating brake rotors BMW E90/E91 330i Front
Part# 328.073.87/88
Replacement Disk #328.24.0057.87/88
Pad # 1061
Prices so far look to be $900+
Uses a 2004+ hat, the euro e90 start year I think
The Direct Drive system from Performance Friction is a 2 piece floating disc assembly designed as a replacement for high performance vehicles used on road or track. The use of a 2 piece disc allows for radial and axial expansion of the disc without being constrained my the hub. This helps eliminate disc warping and judder under heavy braking resulting in more consistent braking with better brake control.
The kit replaces the original discs and retains the standard caliper.

EDIT:
apperently the e89 z4 35 sdrive in USA and 3.0 in Europe use the e9x 330i Caliper, also found on the x1
But whats nice is that they use a 330mm x 24mm sized non Sloptted Rotor that is BMP style: Aluminum hub rivetred to Rotor disc!!!
