Fine-adjustment 0.1mm shim for setting differential bearing preload in the R200 carrier used in the FC3S and FD3S RX-7. When the 0.2mm shim gets you close but not quite, this is the finishing piece.

Available separately so you can dial in preload exactly rather than hunting for a combo that's close enough.
