For the front diff., I use the Tamiya 1 million grease. Kyosho also makes the same 1M and both companies have different lower viscosity greases or oil. The grease is thick and unlikely to leak out of even the stock diff.
For upgrades we're allowed the front output shafts (u-joint), bearing kits, and motor heat sinks. Have to run stock friction shocks and diffs, but can mess with grease in diffs. There's some push to allow for oil shock upgrades but not allowed as of now... but we just had the first race this week so that might change depending on majority sentiment.
Thanks for the tips!
