I'm sorry I might have missed your point. What problem exactly are you trying to solve by replacing the springs? I assumed you were trying to address a sagging suspension
I think I get your point, that a spring has a finite lifetime and a finite number of cycles to failure. Of course you are right about that, and yes a spring that is being worked will eventually "wear out"
But properly designed springs, operating within their elastic limit, have a lifetime far greater that the life of any car. I'd say that fatigue failure of the spring is so far beyond the life of the car that it is not an issue.
And my point was that Saab OEM 9-5 springs are *not* properly designed, and new ones will take a permanent set within 6 months. They seem to operate near the plastic limit and deform permanently in short order.
