I have those and EBC HHH pads, mine work great.
I assume you mean EBC HH that work great.
I have HHs as well.
They did work great, but note the past tense.
I am now a convert.
I did an inspection yesterday, beings suspicious about the rotor look and loss of initial bite and found my HHs to be badly heat checked and also displaying some break out and chunking on the trailing edge.
I know what did it, 135 mph down 3 gears for T1 at the track, hard braking to brake pass faster supersports.
The copper backing was still nice and flat, but had very noticeable heat discolouration.
Still plenty of pad thickness left.
Fine for street use, but not hard track use.
SBK5 Carbone Lorraine's are already enroute to me from LDH's desk at Kyle Racing.
There was no need to wait for the XBK5s as supercede the SBK5s.
