delrin or teflon between leaf springs?

[budman k20]

All the pressure (friction) between the leaves is near the tips once you take the spring pack apart you will see why. I doubt if you cut strips and put them between each leaf that they will stay centered unless you have someting on the sides to keep them in near the tip of each leaf. Save yourself the 40 bucks and the time. Clean / polish the leafs real good near the tips and put them back together that's about as good as its going to get with your stock springs.
