2. The stock setup has a relatively light, fixed-rate diaphragm spring where as the Scorpion kit comes with three sets of six coil springs (42 pound gold, 58 pound gold, 82 pound green, and 100 pound red) that can be used as matched sets or in mixed combinations to get grip and pull in balance and just right for any application. That said, one of the biggest rookie mistakes in a clutch set up is to immediately go with the strongest spring available, which is usually not needed and invariably makes clutch pull at the lever too stout for normal humans. If you really need the stiffest springs provided, you'll most likely also need to convert from cable to hydraulic actuation. Speaking of hydraulics, it's during a shift that the greatest demand is placed on a clutch. As the plates slam home, incredible heat (the real enemy) is generated in the pack that doesn't transfer to the entire clutch all that rapidly. Funny to realize that a "wet" clutch is actually oil-cooled, but essentially that's the way it works. That's why pre-soaking the friction plates in primary fluid is crucial. Oil retained in the friction material is squeezed out, taking unwanted surface heat with it. If the plates cannot absorb and discharge oil fast enough, heat builds and glazing (plate imbedding) occurs like brake fade!
