I got new brake pads and Brembo cross drilled rotors recently. I am not sure if they are Axxis or not but they were ceramic and about $79.00. Anywho...
They definetely do have less dust but I am so picky about any dirt on my wheels I still clean them all the time. It is less dust but still dirty. Kind of like rear wheels. They don't get as half as bad as the front but still are dirty. So if you are buying them to only have to clean about once a week that is cool. But if you are buying them because you are sick of cleaning them everyday, then you are not saving anything buy getting the new ceramic. Maybe just less work each day.
