The problem is that the hardened inserts that the outdrive rides in are not flush with the bottom of the diff housings. They are very hard and no matter what you do they will wear the shim. Nobody sells a shim that is as hard as that insert. The shims will wear until the outer half touches the housing and then they should stop wearing, or at least wear much slower. By going with a thicker shim you can wear into it a ways and still have material left for the cross pin to ride on.

In a perfect world Losi would update those inserts so that they would sit flush with the housing and this issue would go away.
