turn out this is what we were running too.I use Pagid blacks and nobody is harder on brakes than I am. Fantastic on the circuit, great on road.
Noisy till they are warm *(which they never get on road) and rattle like hell in the caliper though.
I just turn the stereo up.
we ended up buying the Perf friction ones to try, so will let you know how they feel in comparison when we go the the ring
