WOW! Now that is getting to the heart of the matter. Simple answer, it depends. It depends on what compromises you are willing to make. It depends on available room to package the suspension (or how much fabrication you are willing to do), how much anti squat you want, how much pinion angle change you can live with, what is the side view angle of the lower arms, how much rear roll steer you want and what rear roll center height you want. All of these affect each other, so there are thousands of workable combinations. If it was easy, anyone could do this stuff.
