On the early Stanguellini Formula Juniors, the rear live axle is transversely located using a pair of wires, NS chassis tube to OS axle end and vice versa.

 

does anyone have any pictures of how was set up, I assume it must have been adjustable? and how did it cope with the change in triangulation (wire length needed) on bump, droop and roll?

It sounds like it relied on wires stretching and tubes bending and twisting...

Not a totally positive method of lateral location, but simple, cheap and acceptable.

It would also have increased the effective spring rate on bump, reduced it on rebound.

All of which reminds me that I once read somewhere that the 30/98s had more flex in the chassis than in the springs...

It sounds to me as if each cable functions like a Panhard rod, but as cables can only be loaded in tension two are required working in opposite directions.

so the wires run from the the two brackets with the holes in the picture (one by the OS damper and the single up stand on the NS) 

to a special nut on the lower damper mount (unfortunately the only one I have has been butchered).

Do you think that shock bottoms out?

Probably when the rear brakes are applied...
