This one's got me good(errr) I just replaced the entire front suspension on my 66 coupe this weekend. Put in new lower arms with roller bearing, camber adjustment kit, new roller perches (Opentracker design), new upper arms with the "free" negative wedge setup again from Opentracker, used 620 1" drop coils, and the Shelby drop, and 12.5" 05 Mustang GT front discs. This is essentially the same setup as my other 66 coupe, but this one isn't working right for some reason. When everything is back together the drivers side drops down so low I can't even turn the tires without hitting the fender???? I can bounce the suspension and no difference. I thought the coil spring might have been bad as the coils are more compressed than the pass. side so I swapped in a set of new 480lb springs (for my 65 Falcon) and I still have the same problem??? I checked the towers, frame rails, put in the monte carlo bar and no change. I can't even mover the car without the drivers side dropping a good 1.5" lower than the passenger side. Any ideas????
