I have tried shimming the diff both ways and with out shims. It doesn't feel to tight. Actually right now the backlash feels pretty good. Its just noisy and notchy at low speeds. If i spin it fast it feels smooth but slowly turning it it feels notchy and even "catches" sometimes. I am going to make a video of it tonight. I actually think its ok and just needs run in. It just not quite as smooth as other cars I have built.
