I am reading through the SuperStreet mag and there're ads for stage I, II, III, and so on clutch. It says that e.g. stage V is only for race use, because it has instant engagement. Maybe I'm not sure how the clutch works, but whats the difference between stock and that aftermarket plate. Does it mean that if I install stage II then I'll have more instant engagement while my pedal is still light? Any other comment on the difference between aftermarket clutch and OEM. Thanks
