Hmmm... clutch package. Do tell. I haven't heard anyone bringing up the clutch. What exactly would a new clutch package do? Where do you find one? How much? Installation?
Clutch package is what you replace when you have worn the old one out with all the upgrades

well you aren't really "gaining" any HP, but your engine is not working as hard to get the HP to the wheels.
with the lightened flywheel the engine will rev and and come down much faster.
there is some debate as to the benefits of a lightend flywheel, but i always thought is was a cool idea, although i have no first hand experience with one.
someone with more experience can probably explain much more than i.
The flywheel is what is termed dual mass. It has a weight inserted into the wheel to give a torsional damping. That is so the gears in the transmission don't rattle on idle. For any performance upgrades this is almost a foregone conclusion that it has to go. At wot, you need energy to spin up the mass. That's energy you want going to the rear wheels, not holding the crank back.
