Rear suspension setup help

[Rondo]

I have a Crossle 65FF - rocker arm on top with a small link for setting toe, lower transverse rod for setting camber, and a long lower radius rod from the upright to about mid chassis. I assume the radius rod creates tow-in as it moves upward or downward? Anything else it does?

How do I set it up? Put the chassis on blocks and move through it's travel? Measure what? Rim face? Seems longer is better but??

This one doesn't keep me awake at night but could not find anything in the threads. Thanks as always for answers from Apexspeed experts!!

If I understand your question.
Lower trailing arm (radius rod) sets "caster" on rear upright. Caster setting controls Bump-Steer.
Set car at ride-height and move up and down from there ( + - and inch should tell) to see if you have any toe changes. Change trailing arms length to reduce or eliminate toe change.
