Shimming a gearbox open

[Frankentruck]

Honestly if you aren't trying to run a stock class and looking for weight and friction reduction, and just running some high power motor, you won't see any appreciable different with any of your versions so far. Oil, no oil, seal no seal, screws snug or loose.

This is just for the satisfaction of the build. I've heard rumors of the transmissions so smooth that they can spin if you blow on the spur. Thought I'd try and make one.

Are there even any classes where a DS could race?

Well there's this one track in NYC ...
