I've been happy with my GM Performance Products (GMPP) clutch. It can handle more HP, but the pedal feel is the same. In the light Goblin, I think it is a lot less demanding on the clutch than the Cobalt was. I read the GMPP is rated to 300hp in a Cobalt, but I'm guessing that is about 400hp in a Goblin.
If you want it to rev up quicker, then get a light flywheel, but if you want less chance of stalling the engine, then keep the heavier stock flywheel.
