Ok. So on closer inspection of a few rear clutches I discovered that there are at least 2 different types. The difference between them being that one has a larger ramp plate(which would add bottom end), has smaller clutch pads, and uses springs that don't have the long side... This would solve the malossi race spring issues discussed here break>

No one had mentioned this before... I'm not sure which clutch came on what model and what the story is with these. The larger ramping plates can not fit on a ciao without cutting the frame to fit it. It's only a millimeter or so bigger, but that would affect bottom end. any thoughts?
