new 8/23/04
I put in some SLO springs code letter L (LOW) along with some Gabriel Ultra struts last week. These springs have the same lb/per inch rating of 155 lbs as the SHO springs. In fact all the GEN 3 Taurus springs have the same 155 lb per inch rating. The load rating differs due to length. It is suggested that the separation of each code letter (27 lbs) is a 1/4" drop or rise.
This is somewhat confirmed by a 1.5" drop that I got by going down 5 steps in springs, from M (MAD) to L (LOW). This is the same drop I got with my other custom springs that were softer and POS(s).
The code R springs are another step lower yet. The ride is good. No bouncing or bottoming out. IMHO a very cheap lowering spring mod. And you can keep your SHO true Ford Blue. :)
BTW the Gabriel Ultra struts are for all Gen 3 Taurii and are only $50 at AZ (with lifetime guarantee) as compared to $150 for Ford SARC struts from FPN.
