Spec 3F Installed Today
The Spec 3 I pulled out isn't worn all that much. The flywheel and pressure plate each had about 0.006 to 0.010 inch of wear. I'd estimate the disk has less that 0.015 wear. Hmmm.
FYI - I had the older version of the Spec 3 (carbon) with six pads. The new 3F is a solid disk.
Having a Spohn torque arm sure saved lots of time--didn't have to remove any exhaust (except one bracket) nor torque arm components.
I'll report back after break-in and some N2O tests. So far, this one looks like a winner.
