I dont think youll find anyone with a comparision on the cusco since they done make it for our cars. On the JIC, It should be a whole strut/coil over set up and *I belive* the struts are rebuildable. If your just getting the coilovers, Id pass on the deal and get a whole set up. From memory on previous posts, the SF is a street coil, SA is more track oriented, and the other two are pure race set ups....dont know if this answers your question but its the best I can do.
