By the sound of your reply, comparing the early one piece swaybar, against the later three piece swaybar, for the same model Spyder, if bench tested, utilizing the entire bar including the billet aluminum arms of the three piece bar, the measured torque required to displace the arms an identical number of degrees, would be the same for the early vs the new swaybar.
Granted, the three piece swaybar has a more direct input to twist the bar, and with that, I would expect the stiffness to be greater for the same number of degrees twisted.
I am sure we are boring many with this discussion. (Sorry folks)
There is a difference in the amount of deflection between these 2 designs, depending on the amount of force. Though this difference is not immediate, nor is it linier once it begins.
Inputting force at the point where the end links attach to the arms (which is what happens in the real world). The amount of deflection at lower inputs will be identical or virtually identical for both bars. However, the amount of deflection (measured at the connection points) will begin to vary at a exponential rate as input force increases.
This is because, as rigid as they are, the spring steel arms do flex. The billet aluminum arms do not.
We are not talking inches or any great visual amount. But a relatively small amount of change in deflection at the sway bar makes a great deal of difference in handling on the Spyder suspension.
