Just to add my $0.02, I think this is incorrect.

I speak as someone whose car is, as I type, in the shop having a Brembo 6/4 bbk installed.

However, I should add that I had ordered the BBK prior to receiving the car (based on my E46 experience) and prior to tracking my E92 recently.

I was surprised at how the stock brakes held up on a track that is known to be hard on brakes. Now I wasn't probably braking right to the limits (mainly because the DCT issue meant I was trying not to trigger abs), but the performance was sufficient that I reckoned a pad/hose/fluid change would make them more than acceptable for most people.

This is because the nature of the degradation in performance (i.e. longer/spongier pedal travel) points more to a boiled fluid/expanded hose issue, than any issue with the calipers being overwhelmed and failing to clamp properly.

As I said, I have a bbk being installed and it looks absolutely fabulous, but the stock brakes are not lacking in power.
