I think the XHD springs would suit your needs better. 1968FormulaS340 ain't a dummy. He's givin you good advice. The SS springs are great pieces.......for what they were designed to do, and that's RACE. They are harsh on the street. Re-arching only lasts so long. There are two methods. Hot and cold. With the cold method, the springs are pounded on a special anvil and arched back into shape. This process does not last very long at all and the springs will return to their previous state fairly quickly. The second method is basically the same, but the springs are heated and then re-arched and quenched. While this does last longer, it also removes some tensil strength. And the kicker? BOTH methods will cost MORE than new springs. Springs are pretty cheap. A couple hundred bucks.....or less and you can have a new pair ready to last a lifetime. There are several companies that will even offer up custom made springs to lift you car right where you want it and give it the ride you are looking for, so there's no reason to "dick around with all that" as 1968FormulaS340 so eloquently put it. I could not agree with him more.
