Checked the oil in my new boxxer race and found these washers on the bench while reassembling, no idea how they fit on but big hole now bottom of damper leg so something’s not where it should be. Bigger lack one is tophat shape and silver&black ones go together by looks of it.

???

Boxxer race by any chance? If so, the top right one should sit inside the compression side lower, top of the hat facing down, its normally painted in place.
Not sure about the rest, probably related. May not be important, re-add the top hat and re-assemble and see if any oil leaks out?

Race yes, the gap inside the lowers does look like somethings come out with paint missing.
Locos sent me a diagram of the others, I guess the tophat thing just needs whacking back in.
