It's true: a "C" on the right, for example, lower than the left one, facilitates taking bends, to the right. However, we are talking about very minimal differences, even just half a millimetre, to be verified at the counter using specific tools. There are no changes to be made at amateur level, but when the level rises, it can be useful to help the chassis bend depending on the number of right or left bends a track has.
