1.Add a plastic motor shim as a cushion to the ATM diff.
2.Polishing the plates can improve the performance but do not just use a polishing cloth plus a polishing compound. You should see how "rough" the surface is and start with a right numbered sand paper. The rougher the surface is, the smaller the number of the sand paper should be used at the very beginning. (ATM needs to start with #400 while Kyosho needs no polishing) Polish the plates in running water and on a perfectly flat surface. You can use a new, thick acrylic board for car setting to provide that sought of flat surfaces. It should be small enough so that you can do the polishing under a tap.(Reserve that board only for polishing). Go down to finer sand papers until you reach about #12000 and start with polishing compound and cloth.
3.Use Associated silicon grease (red words) instead of any "diff" grease because of the small scale of the mini-Z.
4.Regular fine adjustment of the ball-diff is of vital importance. 1/10 ball-diff should usually be tight enough so that you can't make it slip with your hands but that is not the case for the mini-Z. All you need to ensure is the diff won't slip when the car runs by itself. However, once you let it slip that way, there is no return.
5. Running-in the diff needs experience. Running-in a new diff on a track with high traction, with the softest tyres, the fastast motor and the cells with the highest voltage will all lower your chance of well-breaking in your diff. Choose the opposite or at least, use your worst pack of battery.
6. My oldest diff is on the MR02 and it is at least 2 years old without any rebuilding. It is still in excellent condition and still in service. All diffs on my AWDs have never been rebuilt and they still run well. If I were to rebuild any diff, I would only replace the balls but not the plates.
See if I have missed anything you wish to know.
