Considering how much time and effort it takes to grind down the diff cases, f-block and ball cups, is it really worth it?
I have a slightly older chassis with just the standard ntc3 holes and my swing rack required no extra grinding and to me works just fine.
is there any huge difference or improvement to be had from mounting it in the new place? is the difference noticeable to a slightly above average racer? does the difference justify all the work?
