This is just a theory, however when removing my stock TOB (from my Spec 2+) and inspecting the billet TOB included with my Spec Twin disk, I noticed that the Spec TOB does not include the two TOB retaining "bumps"as the stock one does. These bumps essentially attach the TOB to the release fork; when you release the clutch pedal, the fork retracts from the pressure plate pulling the (plastic) TOB away from the PP.
With the Spec TOB, when the fork is retracted, the TOB is floating so it doesn't get pulled back and is free to move in between the fork and PP (perhaps also vibrate freely when the FORL when normally hold it still). Now, this might not solve it completely, but may contribute to the noise.
This seems highly suspect to me. I don't know if I want to try both as pulling the transmission is a PITA.
Thoughts?
