Went ahead and ordered some of the Energy Suspension. After looking around more polygraphite is the same thing as graphite impregnated poly, just a trademarked name.

If you don't mind me asking Insidious, how did you install the zerks? Did you just drill through the top of the a arm and tap it? I think I'd like to do that.
