Optional Shim set of 2pcs 5x7x0.4 for the use in GD2 Gear Diffs instead of WA03 big washers.

The smaller outer diameter of this shims allow more silicon oil behind the Satellite Gear which changes the behaviour of the Gear Diff. GD2 will stay even more consistent with the use of this optional shims, as less heat is generated by less friction.

INFO: GD2 with small shims needs ~x1.5 thicker oil to be initially same stiff as GD2 with std. WA03 washers.
