These new multilingual manuals are garbage!! Any one know what they used? Still build tight like the 2.0 rear truggy diffs?
The std setting is 2x .25 on the left and 2x .25 on the right. But your results may vary. Due to typical molding variances in the manufacturing process, this step needs some individual attention. The important thing here is to shim the diff to have a slight amount of notchy-ness (but with no binding) when building the kit. This will break in rather quickly during your first few runs. Please use the extra .10mm adjustment shims supplied in the tuning parts bag, and add or remove necessary shims to achieve a ring gear mesh you are comfortable with. Reshim after approx. 5 battery packs so the mesh is free with little to no pinion shaft lash for best possible results. This is the best method to ensure a long ring/pinion gear life.
