Caltracs with stock leafs

I would remove the 1 leaf and make them softer.
The CalTracs don't work with stiff springs. They need to give so that the axle tube will twist, causing them to push down on the front of the spring, and lift.
I ended up making a set of springs from old leafs that I had. Car has very stiff set on them and the CalTracs didn't feel like they were doing anything.
