EBC's are crap for anything other than sedate street ridding. Even at a fast street pace, they tend to fade fast. My preference is SBS Race Sintered pads. Vesrah and DP also have some very decent pads along with Galfer and Ferodo...but the SBS's are usually priced less and provide great lever feel with plenty of stopping power that is easy to modulate.
I heard Carbon Kevlar (? not sure about the name, but carbon something) are better than EBC (an EBC sponsored rider told me this ). I am going to try the Carbon Kevlar next time. ~$80 for front calipers.
I installed the axial Brembo 4 pad (998R) calipers and new EBC HH pads at the same time, so I don't know how much of it is due specifically to the pads, but the combination was a tremendous upgrade over the stock calipers/stainless lines/Brembo radial master setup I had before.
