I have been told to go buy the POSIES SuperSlide Multi-Leaf
Springs to lower my 60. Anyone lowered this way?

 

I was also looking at the Posies lowering springs. They look like they are the best deal going. The "super slide" part looks like the exact same setup as the original front and rear springs have. Dimples in the end of the springs for teflon bushings to ride in. I have priced original replacements and they are almost the same price as the Posies with 2" drop. Has anyone used them?

 

I used them up front on my 1950 F-3. The ride is kind of bouncy so if I had to do it over again I would go with a standard leaf pack and remove a few springs for better ride, or do a clip swap. The Posies work ok for short outings but I would not recommend their use for a daily driver unless your streets are really smooth.
