This is a known phenomenon in offroad RWD. CVA, CVD, universals, sliders, and dogbones all have different effect on rear traction as the mating surfaces interfere with suspension travel under load, and thus affect weight transfer. In addition, the angle also plays a large role, hence the idea of spacing the gearbox higher. Also fore/aft angle has an effect, especially notable in touring cars as the front arm/caster block is spaced back and forth. Wheelbase is only part of it.
