I have a Fidanza Aluminum flywheel, SPEC stage 3 clutch, tripple hook quadrant, firewall adjuster, and adjustable cable, and the new RAM Kevlar pilot bushing...around $50...just out but supposedly never wears out or needs lubricant, and is smoother and easier on the input shaft with less chatter. I have not fully broken the clutch in yet. I have around 250 miles on it and it needs a 500 mile break-in before I can get nasty with it. The thing I would say is that my car revs very fast. At first the car is really jerky when engaging the clutch and feels like it is grabbing in a jerky manner if you don't slip the clutch well. As I put more miles on the clutch it is becoming smoother although it still exist, but not as often...or maybe I am getting more used to how to feather the clutch for street driving. I was going for the lighter rotational weight in any manner possible, but I am not sure if I wouldn't go with a billet steel the next time or stock. I am sure that I will have more of any opinion as I drive it more, but I wanted to provide a little feedback to you. BTW I got the flywheel brand new on ebay...can't remember the supplier...for around 270 and the clutch for about the same. Hope that the input helps with any decisions that you will make.
