Don't give up, at some point I will publish how to adapt digressive valved Bilstien struts to the front of a 89-95 SHO, if you have a friendly machinist and ability to do a quick weld its not too crazy. The first time I ran them with half coil cut Eibachs and gen 3 subframe conversion, they were phenomenal the few times I open tracked them but a hair underdamped on the street.
this time around will be trying them with either 200 lb GSR code, or 155 lb front springs, which are closer to what they were designed for, and the Gen 3 subframe (in itself not the end for geometry improvements). On the rear I have new examples of the final design Ford Police/SHO struts with 130 lb/inch springs, aiming for a sport touring combo. Going to run an NOS 25 mm rear bar.
