I am having the same issues after my eibach install. The sound seems to be only coming from the drivers side. At normal driving speed it's not an issue but when driving very slow like turning into a parking space and backing up is when I notice the clunking sound. I also took back the car to the shop who installed the springs and they checked and rechecked everything and said everything seems to be tight. This is really bothering me because it was not there before the drop. The other day I was determined to find the problem my self so I went out and popped the hood and removed the tire. The first thing I noticed were the two lower strut bolts were reversed, the nuts are facing the back of the car as before the nuts were facing towards the front of the car. Does this really matter?........ I am not sure but I would still like to see them the way they were before. Look at this thread and you will see what I am talking about.

I also had my wife turn the wheel very slowly and sure enough I hear the clunk coming from the upper spring strut area when the wheel gets fully turned then she turns the wheel the other way and just before the last turn there was the clunk sound?.............. maybe the spring is not fully seated or the strut tower is loose.
I would like to hear from anyone else who has or had this problem and what you did to solve it or do you just live with it.
I even took it to the dealer the other day to have them look it over and to have an alignment. Three hours later I get a call from the service dept saying they could not align my wheels because of the drop, something about the car being to low to get on the machine. Then he says the reason for the clunking sound is that the springs have been cut to short and are moving around. I said those are eibach spring designed and made for the coupe, I then just turned and walked away. This guy is fool of BS and to tell you the truth I believe they did not want to touch the car because it had been modified.
