I think I just saw some or something like it. Which btw the hpi heavy grease is 30,000 weight...who knows how this compares to silicone oil weight.
But thought I would throw that in.
Also kinda on the subject of the diff, I was reading through hpi japan site and they have the 4 gear listed with this information.
"4 bevel diff gears which show the LSD effect which it stabilizes. Width of setting furthermore spreads by modifying oil viscosity. All the Japanese champions use these parts. "
HPI USA Says this: #33406 Diff Gear Set (R40 4 Bevel Gear)
4 bevel gears make the car more stable under hard acceleration. The 4 bevel gear set-up also increases durability.
If you want to check more r40 parts and hpi japan descriptions, which normally have a different twist and more information.
