Precision 0.2mm shim for the R200 differential found in the FC3S and FD3S RX-7. Used during LSD installation or rebuild to set correct bearing preload and axial end-play in the diff housing.

Getting shim thickness right is the difference between a diff that hums quietly and one that howls — don't skip this step.
