build your own modern style traction bars

You're still heavily reliant on the rigidity of the spring w that setup. Probably ok for the street, but not off-road high torque applications. You need two attachment points at the axle. The front half of the spring can still bow into a "U" as the pinion is forced up, it'll just pivot around the single attachement point at the axle as demonstrated by "rotational force" labeled in fig 2.

Of course it also looks like he only addresses SUA apps, in which case spring wrap is much less of a problem anyway.

strong on the street
Of course its not for off road!
they are in use here
If they can withstand 628 RWHP then they are good enough!

Helped a guy build them but they are a blatant ripoff of a Calvert Bar.
Nothing original there.

Acutually they are rip offs of the slide a link bars from competion engineering.
Caltracs copied them and got into a legal battle until making a bar that isnt adjustable like the slide a links are.

Caltracs are superior to slide-a-links.
