So you are gaining toe as the suspension loads? That's not good if so. From the way your links are mounted in the chassis, it looks like the case.
The inner link needs to be higher than the outer to reduce toe when the car loads in the corner.
As for the c hubs, you wouldn't want them leaning forward, the Awesomatix car runs 4* caster in their rear steer
I haven't had mine on a setup station.
However my lap times instantly dropped .5 sec on a 9-10 sec track.
