Wing drag and lift directional components are only based on the cosinus between wing's lift normal and surface speed. So as long as you are not changing the lift direction like sweeping neither the lift nor drag changes.
As a side note: Drag cubes are normally not used for wings, you will find dragModelType = none in all stock wing parts. So sides are only visual.
f_drag = -v_surface/v_surface * A_wing * f_drag(abs(cos(angle))) * f_mach( mach ) * rho * v_surface² *global_constants
Note: Bold are vectors, all other scalar. angle = angle between v_surface and wing lift normal. f_drag and f_mach are quadratic bezier curves, one to model angle dependency and the other mach related non linear effects. rho is the local air density.
