I have ordered my coding cable and once I have it will give it a try. If I'm honest I am not installing true performance brakes for my 130i, but 335i instead. However, everyone says 335i brakes are better to the 135i 6 pot brakes, so will code my car as having performance brakes.
Gees, those 348mm discs are quite big... also the one pot calipers are kind of huge! will fill my wheels better and should improve braking somehow.
