You can just barely see it in this picture. There is 0.026" of a difference between the mounting surface of the clutch housing, versus where the clutch itself engages the flywheel. I didn't do it, cause I forgot to request it.

Another added bonus to running a turbo flywheel, it is roughly 9/16" larger in diameter. So more clamping surface.
