Worn flywheel end float

Hey Guys , I have a wbx 2.1 that has the bearing surface worn and appears the wear is not even across the surface as you can feel a slight lip about 4 mm from the outer edge.

 The shims appear fine any hints on how this occurs.

 The only force I can think of is the clutch pressure plus general wear from dirty oil etc.

 Anyway im after a flywheel to suit the 2.1 wbx if anyone has one and I am on the sunshine coast

Cheers Guys Pete seq
