I have the CCBs and only hear brake squeaks when car is stopped and then i turn the wheel. I have a 6MT and hear the noise typically at a stop sign when i'm turning. Don't hear noise in straight line braking, but sometimes right before stop when the wheel is turned.
I saw in an earlier thread (i believe SirLoin) had an issue with CCBs as they were different thicknesses - but caused severe shaking when braking at high speeds. have about 2k miles in - and the noise isn't that annoying for me to get checked out - and assumed noise would be part of the experience - along with awesome incredible brake feel and stopping power
