Fitted some Brembo Z04 pads to my blade yesterday. All I can say is jesus they don't half bite!! I'm still running standard calipers, discs and m/c. But the bite compared to the Brembo RC pads is something else. Pinky braking from now on. I'd not recommend these for road use either.
Really, i thought they were awesome in the dry, but in the wet they were pure scary, id come up at the end of park straight at cadwell, knocing on at a few mph's, and find my brakes worked as effectively as 1970's pram brakes. never used them since, stuck to my trusty EBC HH or SBS Dual Carbons.
Could be a temp thing? Still late 20's here even in the rain. But I gave them a go yesterday (it's monsoon here in SG) and they seemed fine. Off to Pasir Gudang this weekend (old WSB track) to give them a test.
