I tried ideas I found in this thread about limiting diffs unloading. I come up with one which worked for me for over a month thats at least 5 race days.
Instead off using shims on outside of large bevel gears I sandwiched tiny o-ring in between shims. Shims are only 0.2 mm thick and o-ring is 0.4 mm. Total of 4 shims and 2 o-rings plus silicone grease. Diff works smooth, but it has a little drag to it. When you spin one wheel by hand, you will spin motor.
