Default Rear Steering - Use Positive or Negative Caster?

I'm setting up my SCX10 with 4 wheel steering and am wondering what will be the best Caster angle for the rear C-Hubs. Angle the top of the C-Hubs back (positive caster) or angle them forward (negative caster). Of course, I have the front set up with Positive Caster but I can think of 2 different ways to think of the Caster on the rear.
I am thinking it needs to be positive also for normal forward steering caster behavior. Correct? Opinions? Thanks.

I have ran zero caster on almost all of my rear steer trucks.

So I should lengthen rear upper links and shorten lowers to accomplish this to keep the same wheelbase?
