Are you certain on this?
I am using the ZCP dampers and stock non-ZCP rear bar with CS coding, and I feel like the rear could use more roll stiffness.
Yes I'm certain. I tested both sets of dampers on a shock dyno (search for the post under my name back in 2018), and how the car drives subjectively aligns with that when you don't have the right rear bar.

If you don't have the right rear bar you'll be missing some roll stiffness with the CS coding.

Your perception of roll stiffness is all relative, so if your swift springs have a different front to rear stiffness ratio than stock, you'll perceive that as insufficient roll damping on the weaker end even if they are both stiffer than stock.
