Default Lightweight flywheel

Hi, first time posting here and my question was if going to a jb lightweight flywheel was a good idea, I'm going to change my clutch soon and wanted to make sure getting a lightweight flywheel wasn't going to damage my car.

From what I have read a lightweight flywheel is perfectly fine. The guy at understeer.com has a bit of a review on the one he installed. I actually have a M3 Fidanza one waiting to be installed on my vehicle, but things are apart at the moment.
