Looked through the article, but didn't read it (yet).
One thought on the lack of springs and shocks, is it possible that they don't need to be upgraded? I noticed in the article that the front swaybar is something like 1.5", substantially bigger than most setups. I know that there are two theories for handling, stiff springs and shock with a smaller swaybar to control body lean, the other is lighter shocks and springs, but a bigger swaybar. Don't know enough to say what the pluses or minuses for either system, only that there are supporters about both. If this system used a really big swaybar, it wouldn't need bigger torsion bars and shocks to create the same roll stiffness.
Just a thought.
