Joe's got it right. Just to add a bit from a few years (ok, decades) in brakes for planes, bikes, cars, WRC, HRC, NASCAR, Indy,...blah.. blah... etc....The organics and semi-mets are both held together with a thermosetting resin of some kind. The resins have a nasty habit or reversing themselves under high KE, so the pads crumble or sluff junk on the rotors. Brake engineers like me call this DTV, disc thickness variation.
At triple digits this really sucks. The symptom is shudder or pulsations. Most bike pads are now sintered due to this issue. Notable exceptions are the rear of the GT (like Joe and I now ride) is NOT sintered. LT is sintered both front and rear. The organics and ceramics from some top firms today are really awesome with very linear torque over very wide ranges of operating conditions. Unfortunately, high load and high temp tend to bring out very non-linear behavior and this happens quickly with a tipping point style rate of change. Simply stated, they may be great then give up fast on you. Hawk, where I was president of their Performance Group, makes a ton of aircraft, clutch buttons, and motorcycle pads for Brembo...sintered. Now OE on Ducati and Aprilia. The newest Hawk sintered has some very good characteristics. They may launch an aftermarket line in 2007. So far, most of their work is OE, for example HD is mostly Hawk sintered pads in Hayes calipers. Hawk is now one of my clients.
With ABS an issue for us now, I suggest keeping your pads as OE. Many love the EBC. Perhaps there is a reason why EBC does not supply Brembo?
I have not raced EBC nor did I put EBC in my LT or GT. If EBC makes you feel good, great. ABS adds a system compatability issue predicated on torque rise rates and stability. Friction varies with load, speed, temp, and pressure. For those of us who run fast, loaded, and pull high decels, we may find OE wanting in some regards.
I have also worked with Galfer and they do some great things. The fact that their MD is an old racer of 2-wheeled machines helps. Last time I was in Barcelona, he took me and SO out for dinner. They understand high speed and they are riders.
I recently ran the Hawk ceramics on my Mini Coooper S (all four corners) and they were amazing. Zero black dust, dead quiet, and sweet bite at very high KE.
You can buy it at Tire Rack. But, I digress.
IMHO, good disc pads are cheap compared to one event of not stopping in time.
SO and I ride together a lot and I want the best brakes I can find.
