Having a look at the worlds pictures I saw many guys using steel balls in the diff (at least thats what it looks like, silver shiny balls) is there any advantage in steel balls? I thought ceramics are the way to go?
In the R5 manual there are put 8 balls in the diff. How many would you recommand for modified? Do you even use both rows (inner and outer ring to put balls in or just the inner or outer ring?)
Sorry for the stupid question I m new to 12 scale
