You need to define your goals, and then design a plan to achieve those goals.
Low speed rock crawling (
shorter wheelbase + wider track)?
High speed cruising (
longer wheelbase + narrower track)?
City car under 35 mph where aerodynamics are less important?
How much HP are you working with?

Aerodynamic Drag - Craig's Website at Backfire.ca
I think once you fit for driver and passenger packaging, and width/track and length of wheelbase for handling, then aerodynamics can be applied.
Or you could come up with the perfect shape and just squeeze people in their any which way.
Your choice, your decision, in the end it will be a compromise of sorts.
