I have SS springs in my other car and I prefer the ride quality of the Calvert split mono leaf springs. The Calvert linkage rattles when you drive so it is noisy, but the ride is nice and smooth. I think the split mono leaf design is far superior to the super stock spring design. With the split mono leafs you can change the spring rate and/or the ride height fairly quickly. SS springs are difficult to work on unless you have the correct tools. Most people never take apart a SS spring pack to change the ride height or change the spring rate. Individual springs aren't easy to come by for SS springs while Calvert has a full selection of mono leafs on the shelf.
