This is how one of our resurfaced flywheels look. It is cross cut on a circular stone lathe. You see the circular pattern radiating... These are raised ridges from the process which the clutch disk will wear even after a proper break in. Until then you have a "spoongy" sufrace which does not have as much surface area as a broken in flywheel with a flat surface. This type of resurface gives you about the best break in when it breaks in. Until then, like I said, less surface area will promote slip under good power.
