I need new rear springs. Originals are getting saggy, one side worse than the other. It was in the "plan" for the future but I'm moving up the schedule. Has anyone been disappointed with the Hotchkiss rear springs on their E-body or is everything peachy? I'm a little concerned about the 1" drop but I think I can deal with that on the mounts if I have to. I am working on a full redo with larger torsion and sway bars. Obviously they work well in their Challenger but I'm not buying the full TVS kit. Is 160lb spring rate a good place to be? Car is a 73 Cuda with a 340. Tires should be 295/18 front and rear when the budget allows. Running road courses in the Midwest and auto X are end goals.
