Rear shock angles?

[11jcr51]

What does moving the LR shock in board do? do you have to move both the FLR and the LR? what about the RR? Does putting more angle on the RF allow it to smash down harder? This is something that has always troubled my mind

changing angle on your shocks changes your roll center to an extent. how much depends on the angle, as well as other factors. on left side, straight up is going to make the suspension more effective and let car roll over easier (moves roll center more left), angled in takes some roll away by making suspension less effective (moves roll center moves right). The shock carrying the spring has the most effect there. Right rear is opposite, straight up pulls roll center right (less roll), angled in moves it left (more roll)

I'm not versed in front shock angles.
