We're all serious about improving our chassis rigidity but some don't do much but either buy whatever we think might work or just complain manufactures don't provide reams of data that meet some unattainable standard and deride those who buy them anyway without the "proof".

Here's a fairly straightforward means to measure the chassis Torsional stiffness.

It would be helpful to everyone and a great reference to have a record of everyone's a car's torsional stiffness and what "mods"(if any) they may have.

It's on my to do for my Swinger.
