Just in case anyone is wanting a new clutch and you don't really want to convert over to the non-modular style, here's a way to get a Fidanza flywheel and upgraded clutch.
I got this from Howell two weeks ago. Waiting to buy a Phantom Grip and install both at the same time.
I couldn't get a good picture of the back of the flywheel for some reason, but you get the idea. The entire weight of the clutch pack is 14#. I believe the stock flywheel is like 12? Can't remember.
