Spec twin original did not require a shim. The clutch was revised about two years ago and the stack height was changed and it now requires the use of a shim. Call Spec directly and speak with Jeremy for conformation.

I bought mine about 10 months ago and it came with the shim. I have bought clutches before that came with a shim but it was only for guys installing it in an F-body.
I'll use it.
I'll use it.

I have the PT trim disks. Mine are now carbon/carbon also.
I did have the SS organic disks but swapped them out since I raised the power and knew it would only hold temporary.
The full metallic is the disk for track use only and not very streetable from what I did research on.
The ST is one step above mine but I'm sure comes with the metallic disk.
