I noticed on SHOnut, it's mentioned that the fibertuffs can eat a steel or billet flywheel... How bad, and what are the chances of that actually happening? And with I be better off with a different clutch?

I believe that is referring to the discs with the metallic inserts, not actually the fibertuff discs themselves.

Per SHONut's Website: "Note also that the metallic lining does not wear like an organic or Fibertuff lining but it instead wears (eats) the iron/billet steel surface, perhaps to the point that it cannot be reground."

The 9-puck fibertuff clutch is an amazing clutch, even with a SHOShop 8-lb. flywheel. What Josh was refering to was a metallic clutch disc or a special order Fibertuff disc with a metallic lining on the flywheel side and fibertuff lining on the pressure plate side. The metallic lining will basically eat away at the steel inserts in a flywheel like the SS or Fidanza ones. But they can be swapped out when they need to be changed.
Definitely go with a 9-puck fibertuff if you are looking for something a little more grippy than stock. It all depends on what mods you are running or plan to run and how much grip you are going to need.

I have the total clutch package from SHONut in my 92. HD PP, Ceramic TOB and 9-puck disc. Still have the OEM style flywheel. If you study the design characteristics of all the components you will appreciate it far more than the stock clutch. But it doesn't drive exactly like to stocker and some people might object to that. I have a slight vibration at idle that I'm now used to. This new clutch is more grabby and easier to launch than the OEM. Absolutely no slip and easily spins my 235 Nittos. Car has a 3.2L upgrade. Good luck.

You wanna see a vibration at idle?? :ruhroh: Try adding Aluminum Subframe Bushings and SHONut EXTREME motor mounts to that equation. :D I was amazed how much more the car vibrated with the Extreme mounts in there, but I'm starting to get used to it and I love them!

I have Alum SFBs. The rear motor mount is basically fixed for all intents and purposes having been shortcircuited by using a nut/bolt combo through the metal casing. I suppose those are contributors since there is less isolation from the drivetrain to the cabin, but my stock clutch didn't have that feeling.

Anyway it's no big deal at this point, and I'm enjoying the "new" clutch.

Yeah, but have you noticed a ticking noise coming from the tranny at idle without the clutch pedal pressed? From the words of Josh T. the noise is normal because of the metal-to-metal clutch spline insert, but I was just wondering if you've heard it too?

Not really. But do I remember reading here somewhere about the unique design of the clutch disk with the metal spline insert.

what I'm gathering from this is that the clutch eats up the flywheel. That's not good for anything, especially with flywheels not being cheap. :slap:

AND the steel insert for the fidanza is exactly that, an insert. It is meant to be replaced when you do a clutch. Don't know how much it is, but it certainly can't be more then $100.
