If you offset the torque rod proportionally with the axle ratio, the left/right
torqe reaction will cancel and the car will react more neutrally, especially if
a little softly sprung, and you won't need a positraction (put one in anyway).
It is also easier throttle steer turning left and right if it's neutral.
The angles from the side determine anti squat and weight xfer - just look at any
drag car 4-link. W even tried a three link (two low and a high offset pull rod)
with a jacobs ladder panhard..
Good luck Tom
