Ceramic is the brake pad of the future, but remember, thats why they call it the future, because its not today.
The Ceramic Pads are suppossed to supply the same or better braking performance, with no noise and almost no dust. The ceramic material should stand up to heat much better, so less problems with heat damaged brakes.
BUT, I keep seeing reports of people having problems with Ceramic Pads, the pads cracking or the rotors warping and developing hot spots, OR the rotors wearing down way to fast. Some people say they never have a problem and the ceramic lives up to the claims of no noise and little dust, while others do have those problems.
My guess, the ceramic technology isn't fully developed yet and the ceramic pads can't stand up to abuse, they'll do just fine if you drive like a little old lady, but your thrashing brakes, the ceramics won't hold up. Nor is the rest of your brake system designed to work with ceramics, under extra stress the different ceramic material may tear up the rotors.
I'd stick with good quality semi-mettalic pads. In a couple of years, when I start hearing more good things about them, I may try some ceramics, until then, I'll stick with the technology the rest of the brake system is designed for.
