Yes the Panhard bar controls RC but because it moves in a odd arc on cycle and articulation at speed if travel is great it causes odd handling characteristics especially on the off side. This is usually not a big issue if it can be held at flatter angles. This is obviously constrained by the drag link on the front as bump steer is something you just cannot compromise at speed but it can be improved dramatically. On the rear is can be made flatter or near level but its length is compromised by shocks being fitted behind the diff. To fixed this put shocks infront of the diff so a very much longer panhard bar can be used. The 4 link addresses this issue with link control so angle change is a lot less so axis angle changes little in comparison. Roll centre to COG does help roll resistance due to weight transfer. but this isn't exponentially equal to the separation so there is diminishing returns as it gets higher. As I understand the concept RC height to COG causes resistance or slows weight transfer from COG but it doesn't really get to a point then extra weight gets transferred so it tips quickly it just slows the process so you can use springs and shocks to adjust the roll speed or swerve speed to a level your like so again how it feels to you. Sway bars are a thing you use because they fix a roll compromise you think is a issue. Race cars use these bars to keep the suspension within the ideal design geometry but also to make the car a lot more responsive to swerve loads or changing loads. For us it can help COG issues on off camber situations but really it is very minor, unless the roll centre is below the axle.

Until next post lol when I have more time.. I have written this in a hurry.
