Back cambering

[halliwell]

Can someone give me details and diagrams on cambering adjustments for rear of my s12, seen a while ago somewhere slotting out to gain adjustment, horizontal and vertical.
Has anyone tried removing rear shocks and replacing with coil shocks angled to inside the chassis leg, all will have to be fabricated ofcourse, but i dont mind having a play, this type of configuration should give it more bite from sideways traction.
Anyone got any thoughts Cheers Fraser
