If you jack-up the left front tire (not just the frame) at the ball joint (carefully) and the right-front tire comes off the ground you have a mighty strong anti-roll bar!
If you jack up the left front frame and the left rear tire comes off the ground, you have a fairly stiff frame.
Our McLaren's mono-cocque chassis approaches 10,000 FtLb of torque per degree of twist, front to back. For sure the all alloy Kirkham is quite similar, by design intent. Don't know about the "regular" chassis. Perhaps the SS is stiffer than the mild steel...
Our AC Cars Chassis ('92) is much less than half that amount. It already has lateral internal stiffeners (plates) welded in place. Didn't keep the measurement data from the tests. Sorry.
