I have no issues with either the calipers or rotors. I plan on going with the Z1 kit at some point for the weight loss alone.
I have really put the brakes to the test, doing some stupid driving, and they didn't fail me.
The only negatives that I have seen regarding the sport brakes are that they can get hot and the stock fluid can boil during track sessions. Otherwise, they are regarded quite highly.
