I just had a OEM spec Exedy clutch and the 7.5Lb Fidanza flywheel put in a little bit ago, and I am impressed by it. I had the assumption that I would stall a lot at first, but it seems easier to drive now than before. The throttle response is awesome and the revs drop really quick. I have not had a chance to launch with it, but from the way it seems now I will not be disappointed. I would suggest this to anybody. The revs rise really quick and drop really quick as well.
