Quote: We can armchair engineer this all day long, but the fact is that every part of our chassis stiffening package was tested and bench marked, and delivered something like 9800# per degree of twist.
CR
Just curious, what's the degree of twist for an unstiffened chassis?
Honestly, I haven't been able to locate that data, there's a ton of it to go through...
The thing to understand is that the data collected was done by an independent company that specializes in vehicle dynamics and optimization... The rating is based on an industry standard, kinda like the way manufacturers give you a HP rating...
I don't know that they used the 4 post for torsional testing, I believe that was done on that static rig. The 4 post tested for shocks and spring rates, sway bars, tires stiffness, they even found a vibration that would be near impossible to find without it... Turned out to be flex in the rear upper shock mount and was fixed with a simple gusset.
Hope that helps...
The video states 9800 is that of the unstiffened chassis, equal to a modern day sedan. The stated goal was 15000, equal to a modern day sports car.
