Do springs get "Tired" after so many K miles?

Looking at buying some 2nd hand Eibachs from a P1 but they've done 70-80K

Can springs get "Tired" - if you get me? Or do they have a lifetime guarantee

cheers

IIRC the effect known as 'sag' becomes more pronounced with more miles but my how I do not know.

No doubt someone on here will be able to explain further.

The spring steel suffers a degree of metal fatigue over time and some stress corrosion too and loose some of the spring rate because of the weakening. They will eventually break in severe cases.

Remove some 'tired' springs, replace with new 'like-for-like' springs and the car will ride much higher after fitting.
