I've used EBC HH and CarboneLorraine xbk5. The EBC's were ok, same as stock I think. But one thing I didn't like: unless you were braking aggressively, the EBC's always squealed when it was about 80 degrees outside. I thought the CL's were a better pad. And they didn't squeal when in that certain temperature range. . Another thing, they have a ceramic lining on the entire back surface, and I think that helps with heat dissipation.
