I see setup sheets indicate adding 1/2 oz there and 1/4 oz there, but how are they determining that? left to right balancing is easy to understand, use chassis balancers along the centerline of the car and place the weights accordingly. what about front to back? Do you balance in a way to give the CG dead center front to back and side to side, or is it different? do you measure overall length and divide to give centerline?

would you use this to balance?

or some other means?

What is everyone's take on this?
