Beware of Eibach Springs Breaking

I had a clunk in my rear end going around turns when there was an elevation change. Inspected the suspension yesterday and found the rear eibach lowering springs broken, see below. I have at least 50k miles on the springs. So for those with Eibach springs, keep an eye on them.
I only had them installed in the rear, stock springs up front.

Installed these new or bought 'em used?

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

That's pretty bad, do you happen to know if/remember if you hit any major pot holes, perhaps at speed, or something like that?

I broke a stock spring and bent a shock on my 2004 F150 Fx4, and the spring looked almost like yours do, except for an F150. However, it was leveled (so the shocks were stressed a bit more) and I was doing ~70 mph off road, and jumped the wheel into a major pit, and then bounced it out, while maintaining speed, so that was a pretty understandable break.

I drive on NJ roads and there's plenty of pot holes, but nothing stands out that should've caused this. There's no reason they should've broken besides poor quality.

I searched and apparently this has happened to quite a few others so it's not that uncommon.

Looking at the failure points in the pictures,  it looks like the springs have just about rusted thru which likely resulted in lots of fatigue cracks and ultimately failure after so many load cycles.   I've never seen a spring rust thru in just a few years/that few a miles so I suspect it to be a manufacturing issue on Eibach's end, likely lower quality steel or improper corrosion protection.

I did a quick google search and saw that there were a few others (different cars, different springs) that had the same failure. 

I suspect it's a manufacturing issue as well. 

I guess I'll be going with H&R springs next.  I can stand how high the back end is with the stock PP springs, skyjacker mode.
