Hmmm, I wonder if a length of square steel tubing would be more effective than the angle iron? How much torsional rigidity does angle iron actually have?
I think that depends on how it is sized, right? Fully boxed might allow for a smaller sized piece. Can square tubing be found in spring steel?
if your looking for material, speedy metals is almost at your doorstep, doax.
angle iron doesn't have much twisting resistance whatsoever.
any progress on idea #2? care too share? maybe missed the post.
Yeah, it will depend on the size of the tubing and wall thickness. Same with the angle iron, it depends on the leg length and the thickness. It also depends how its attached to the torsion beam as well.
I've used Speedymetals before. This time around I used Midwest Metal Warehouse. Its about 3 miles from my house.
There is also the fact that you do want it to be able to twist. You don't want to put something super solid in there. Its gotta balance out.

Some folks in the Fiesta/2 crowd have actually said that the clamp-on Racing Beat sway bar created too much oversteer. But I have a hard time imagining how bolt-on units like the Corksport and DDMWorks are able to stiffen the torsion beam.
saw these control arms just like those ricey civics fabricated for the mirage. found on a thai fb group
So why would you not go to a wrecking yard and cut the internal sprung steel tube out of a existing rear beam,suzuki swifts from 2005 onward have a tube that runs across the beam from side to side and is placed within the v section of the beam, lots of econobox front-wheel drive cars already have a torsional bar within the v section of the beam.
If you want to get really technical look up the 1998 super touring cars they came up with a adjustable blade system that went from the lower rear shock mounts to the point on the opposing side of the car where the beam meets the trailing arm in a crossover pattern, this not only made the torsional load of the beam adjustable but also added sideways ridgidity to the trailing arm set up.
The aftermarket type sway bars that bolt up under the spring seat then go forwards to follow the beam would also add to the sideways deflection if mounted well
