"It could just be his solution for a replacement spring setup. It has no function as a camber compensator."
Yeah, that's why I'd love to see some build pics. I think that the transverse spring's double function as a camber compensator would entirely depend on the spring rate. Honestly, my Berg unit is flimsy crap with a ridiculous lower pivot point. I'd much prefer a tunable transverse progressive spring set-up (in addition to the stock torsion bar) if one were tested and made available.
"With the double bolts on the spring pack, again it looks like it would, but can't articulate one side to other."
Again, it depends upon the spring being used. Even with the rigid lower center mount, there would be a degree (a tunable degree) of spring wrap in addition to the natural end flex at the spring eye. A pivoting center mount would solve that problem and provide a progressive option to what is now a thin band of metal.
Not this this is a solution to a semi-solved problem as it sits, but I'd STILL love to see how it all comes together. I know that there's SOMETHING there for me. With alterations for sure, but I'm extremely worried about the chassis under the Fiat and how the power is going to stay on the ground. Looking everywhere I can for adaptable solutions, you know? If a transverse trailer spring can be adapted and tuned, fine with me. I even love the whole look of it.
Of course, I ALSO love the look of this brute, so go figure . . .
