Let me try again

You can get build springs with different wire diam, spring diam, length, coil spacing and pick all these variables to get the same stiffness (K) rate, to the comma, for both.

Then - How are they feeling different on the track? What are the physics behind that difference, and what makes them behave differently beyond the simple F=KX?

I have yet to find a proper explanation on this forum. Who will rise to the challenge?

Thanks,
