As far as the spring rate,,,,take a twenty foot long piece of tubing, and support at each end with a jack stand,,,now push down in the middle you will have plenty of spring to it,,,,now cut it and half and do the same thing,,,you will not have the spring anymore because of its length,,,,now when you split a mono leaf,,,you do EXACTLY the same thing. Leaf spring cars with a traction device love the soft spring,,,,shock adjustments respond better and so do tire pressure changes.As far as advantages,,,, I see none,,,only disadvantages

If spending money that is not needed makes one happy,,,go ahead and buy the expensive stuff if that makes life easier,,,, but I can tell you from experience its not needed.

As I said earlier,Keener doesnt use them,and he pretty much can buy what he wants,,,but he has a STOCK spring for a reason,,,and his cars are as fast as they get he has those for a reason

I’m not looking for an argument here, but I disagree with some of your theory. I agree if you take a 20’ long “spring” and cut it in half it will be much stiffer. But the Calvert spring , even though it’s two pieces, it remains the same length. The distance between the load bearing points of the spring remain the same, that is not cut in half. The affect is completely different. With a two piece spring you can have different spring rates or arc ahead of the axle and behind it. So you can keep the front soft so it will work better with the traction device as you stated. Then ride height can be adjusted with the rear spring segment.
Adjustability is one of the advantages of the caltrac springs.
