I have Carbotech's and they needed bedding in. Smoked and smelled horribly during the bedding process. Now they work great and squeal like a pig, but only when cold. Unfortunately, lots of my driving is in traffic and they often never get warmed up. After a track day where they get used hard the squealing stays away for a day or two. Dust is not a problem. My goal was no fade, consistent eyeball popping braking and good initial bite and that's what I got.
