FC Chassis Torsional Stiffness
To share some of the FC related information for the car we're building into a dedicated, stripped, track car.
We bolted the rear of the car to the concrete and measured the torsional stiffness to get a baseline reading.
The baseline reading was 3031 nm with the car completely gutted.
We then fabricated a rollbar and harness bar and welded it into the car and re-measured
The updated measurement was 4480nm, an increase of almost 50% rigidity.
We measured using various weights up to 360lbs total. It was a fun experiment, and gives us an idea of how much, or little, chassis flex we'll be working with once we get the car fully assembled.

I had the same thought about how much more a cage would provide, but we have no intentions of adding one at this time.

This truly is an interesting thread, but I'm going to close it since it's a repost.
