*just my little knowledge*Getting a new flywheel is just the recomended thing to do fi you replace the clutch you don't have to do it. It should be resurfaced or something. As far as the flywheel it depends on the engine if you have a engine that thrives on hp not torque (b16) you could take a lighter flywheel. *Not a diss to anyone* If you have a turbo car A lighter flywheel will help spool faster. I would guess if you don't plan on putting down no more than like 220-180hp i think that would be good for a stage2. That is just my opinion, anyone correct me if i am wrong.
