Stock springs (upper set) already have factory steel spacer. You'll need to increase spacer-length with a PVC version to make up for shorter stiffer spring of either homemade or bought variety. What's difficult to see is small washer between factory spring and spacer. Be sure to carry over that washer to new springs. Aim for about 1/4" pre-load like factory configuration. That is, spring+spacer is 1/4" longer than space inside fork, so you have to compress stack about 1/4" when putting end-caps on.

For your weight, you may want to remove only 8-coils from factory spring (Gary and I are about 170-lbs and need 10-coils removed).
This is FANTASTIC information and I am super grateful!
