This is not a quantitative stiffness analysis.

We do not know enough about the torsional behavior of the vehicle to get a hard, reliable number for the torsional loads a vehicle experiences on track. So we're going to pick a reasonable number, and hold it constant through multiple tests and see how the results compare.

What this means is the numbers do not match up to the real world. They are only useful for comparing between tests.

This sort of iterative analysis is a bit of insight into how we design. Torsional stiffness is just one of many things to consider when designing a cage, but you can see here why certain things are the way they are.

Phenomenal description of computer generated testing performed and how it can relate to real world results. Thanks for sharing Jake.
