    Simple one really. The roll center of a triangulated 4 link is located at the convergence point of the upper links, not the actual axle mounting point, correct? For it to be the same as the axle mounting point(at least at ride height) the upper links have to be parellel to the ground correct?

    Debating 3 link + panhard and double triangulated in my own head at the moment, Roll Center is of course the obvious advantage.

    The answer is, it depends.

    Single triangulated on top with parallel lower, the roll axis is parallel to the lowers and passes through the intersection point of the uppers. Roll center is where a line perpendicular to the ground passes through the axle center line and hits the roll axis. This is the point that the chassis appears to rotate around when articulating, ignoring other geometry changes.
