I have dearched a set of SuperStock springs. I took 4 inches out of mine and it sagged another inch. They were on a 68 Dart small block car that ran tens and I loved them and was able to get a 1.39 sixty foot out of them with a 10 inch tire.
Thanks that sounds like they are working fine for you. Think I'm Going to have 2.5" taken out of them and use a shim kit to correct the pinion angle if required.
