You are aware that a swaybar IS a spring in itself... right?

The thickness of the wire is what applies the resistance (rate) against applied force.

The thickness of the wire is what controls RATE.

Larger coils spread the same resistance (rate) across a wider area. This is why you hear people define a BB spring feel as 'different', 'smoother', etc. A larger coiled spring (same RATE, same wire diameter) does the same job easier than a small spring. Progression is a different matter entirely.
