IF you have a spare $1,900 maybe try bmw's performance brake kit p/n 34110444772
You also need to re-code the ABS system for the larger brakes when installing the Perf brake kit on a 128i. You can also order it thru BMW when you order the car. BMW NA installs all Performance parts when the car hits the port. Then it arrives at your dealership. AND you have the same four year warranty on these parts.
