XRAY - Model racing cars

as in the tittle which position gives best traction with new clamps. as i archieved it's R3 & F3 with 2mm shims.
I need lot of rear traction and stability. (technical low grip asphalt in modified [5,5T motor]).

our track:

try shortest possible linkages, 0mm shim in front and 1mm shim in the rear, that is how I use it on low traction tracks

haha i was drivin' with longest and highest. that is the problem

Sorry Martin, but you have in your setup book on page 27 written that:

B) lower the roll center (lengthen or decrease the angle of the links)
• Decrease the height of the camber link OUTER ball joint by removing shims in between the joint and the hub.
• Increase the height of the camber link INNER ball joint by using one of the upper XRAY Quick Roll Center™ positions on the shock tower
• Lengthen the camber link by using one of the INNER XRAY Quick Roll Center™ positions on the shock tower. Remember to mount the
outer ball joint to the OUTER mounting position on the hubs, and adjust the length to achieve the proper camber angle.
NOTE: Camber gain will decrease as the chassis rolls. We recommend that the camber link always be angled so the outer ball joint is higher
than the inner ball joint.

now I´m a little bit confused.
But honestly spoken, sometimes it is too difficult for me to understand the link angle and roll center issue
