I've asked this question on numerious boards.. but no one has given an answer yet... maybe the guys that lurk this forum can help.

I brought an aluminum flywheel for my car.. and I only have tommorrow to drop it in. What I need to know is do I need to have this balanced out the box, or can I just bolt it in. On the flywheel the sticker says it needs to be balanced to match the original flywhee; before installation, but in the notes it says it's already balnced to the correct balance... What do I do?
