Well, we did extensive tests and measurement on the 991.1 GT3RS between steel and ceramics and even if ceramics progressed, on the long run the steel are still cheaper to run by comfortable margin.

 

True, unfortunately, it is not the wear and tear but simply dirt, little stones etc. from the track getting between the discs and the calipers and then you are done ... or, I do run on steel brakes, but once in a while overdo my driving and end up with a solid "metal on metal situation" and then I get angry with myself (or my own stupidity), get new steel discs and that's it ...
