I'd like to say that I've owned Eibachs on my current and previous car. That previous car was in fact the reason I got them for my current car. On my current car, I bought my Eibach springs through an online dealer in March 2004. The springs are warrantied for at least 10 years. In May 2008, after my car had been parked for awhile (gas prices are high), I drove less then a quarter mile from my home when I realized something was very wrong. The front passenger spring had snapped near the bottom coil. The broken section wrapped around the strut and was clanking around in there, making considerable racket. I got the car back home and checked it out, where I first discovered the damaged spring. I called Eibach's customer service the next day regarding warranty information about getting a replacement spring. They informed me that I'd have to PAY for a new spring, pay for the shipping of the new spring, and then pay to ship the old spring back to them where they would look at it and decide if it was a warranty claim or not. If it was, they would then reimburse me, if they decided otherwise, my cash was theirs to keep. To me, that's a bad situation. I pay money, they take my money, and then I'm supposed to have faith in them. I instead offered to ship the old spring back at their cost using a return shipping label after I got my replacement spring. They said no. Then to top it off, the young customer service girl told me that "our springs don't fail", and I responded by saying that sure isn't true because I was holding a piece of their spring in my hand. She got mad at that comment and hung up! She hung up on a customer! I called back, spoke with another customer service agent, told him what happened, and he tried to make an excuse for the previous girl by saying that they weren't necessarily paid to argue with customers. I then informed him that that's exactly what his job is - customer service. I then asked to speak to their supervisor. I was transferred to his voicemail and I left a message. I waited a day and never heard back from him. I called again and left another message. To this day, 3 weeks later, I've never gotten a return call. This company I had thought made a quality product. But if you do end up having an issue, they don't seem to want to honor their warranty. Because of the issue with their customer service, and not the failing of the part, I probably wouldn't buy another Eibach product. Thankfully the online retailer I bought the product from stepped in and ordered the replacement spring at their cost and politely took care of me because as one of their agents said "we'd like to keep you as a customer." And they have.
