I used an idea from a engineering book but I suppose that the angle of the
rod is too large.
I drove into a McDonald parking when the left rod snapped.
With one working rod the on-off-throttle steer was back again...greatly more
than it was but the car felt much better.
So I'm going back to the stock situation and remove the rods.

And thank you all for input. Learned a lot.
Chris, as I recall from my old DP car with a Detroit Locker
differential; the car would squat to one side or the other under
acceleration/deceleration; after I installed a set of torque rods the
problem went away. It is important to have the axis of the rod parallel
to the frame when the car is at half suspension travel. That should
minimize surprises as the suspension hits the limits, as Duncan said
below. By the way, it appeared from your video that the rods were
welded to the top of the axle. Mine were mounted to a plate under the
spring pad; the front of the rods mounted to a bracket I welded to the
frame.
I have some pictures of a Traction Master rod like I had installed which
I can send if you want them.
Gluck auf!

Chris,
Does the rod's arc of movement exactly match that of the axle? That is,
does the front mount of the reaction rod use the same axis of rotation as
the front eye of the spring? If not, it's trying to twist the axle relative
to what the spring is doing, creating resistance to movement, adding roll
stiffness.
Another approach might be to clamp together the front leaves of the spring
but leave the rears alone. One other solution I've seen (on a Sunbeam
Tiger) was to wrap the front end of the second leaf around the spring eye
bushing (inside the main leaf eye, and using a smaller-diameter bushing),
effectively doubling the stiffness of the front half of the spring.

Hi Guys,
I installed rods to the axle.

The leaf spring is now calmated but the car does oversteer badly.
Seems to stiffen up the suspension now.
I'm not sure if I should maintain that idea.
Cheers
Chris
