Stock vs aftermarket!

Umm I'll let some more senior/experienced members to articulate the answer technically. In short, like other members have stated, its the shocks/dampers that potentially needs early replacement, not the spring.

If or when that happens depends on how much shorter AND the stiffness of chosen springs, like dp3ngu1n said

This. Unless the spring actually breaks, it will not need replacement at any point. It's a spring. There's not a whole lot that can happen to it. The shocks may wear out early. They may not. It really depends on how low you go. A little bit of drop (Swift, Eibach, etc) does not seem to be causing too many blown shocks, or we'd see a whole lot more WTB:Shocks threads in the marketplace. If you slam the car, it's likely you'll eventually damage the shocks. It may be in 30k miles, or 3k miles. If you want to disregard correct suspension geometry and slam the car to the ground, just buy coilovers and skip aftermarket springs.
