Got about 30k miles on my Eibach springs. I do have EDC. Over time, the ride has gotten harder but I'm thinking it has more to do with my tires wearing out than my EDC shock wearing out. I've never felt like I've bottomed out and I don't see any fluid leaking from the shock body. I will need to replace my tires soon since my Vreds have 28k miles on them and when I do I will know for sure if it was the tires or the something else.
