For a serious runner it's possible to replace the diff balls with modern ceramic balls.

What size are the balls and are they the same size as the ZX-5 balls? I want to get some for my two runners

Thanks Jeff and j0pp3. I did as recommended, black grease for the thrust and Kyosho diff grease for the ball diff.

I'm still unclear on how to properly adjust the diff, though...the aforementioned instructions are useless because "the diff body should not turn idly" is arbitrary and makes no sense. I got the diff outdrive on one side to reverse-rotate nice and smooth to the other side, but it seemed otherwise to be quite loose--maybe that's how it's supposed to be? When I tighten it even just a bit more, the reverse-rotation seems to have too much friction/resistance, and a bit more tight and it feels scrapey, which can't be right.

How do you guys recommend adjusting the ball diff, in empirical terms if possible?

With dremel you can do what ever you want. And the finish is superb.

Word! Next part to create will be a Rear Plate (L). For that I will use an OT-114 as a blueprint even if I won't use it to mount a mechanical speed control. And after that I may try to do my own chassis designed to use saddle pack LiPo's but by then I think my runner will have it's own thread :)
If its any help I have had Fibrelyte make me this SWB chassis, along with some other custom parts which will turn up in my thread if I start this build next now the SP is nearing completion

The build thread still lives on here https://www.kyosho-optima.com/midse.html

I referred to it many times during my ongoing Turbo Optima Mid SE thread.
