1) the tightly wound coils unwind over a bump as they lengthen and slam into each other because the springrate of those coils are really low, thus they compress/decompress too easily ( don't even see why eibach used those instead of linear rate springs).
solution could be to use the coil wrap like someone suggseted
2) the 2 strut bushings (inner and outer) might be too worn and compressed, thus there is play and it allows the strut or something to bang when the suspension moves.
solution would be to add washers or to try new bushings and washers to fill up the space
3) There might not be enough suspension travel for isntances where the spring lengthens (not compresses). I believe this occurs when the springs are installed on a low perch setting, thus you barely compress the spring a little to get the top strut mount on... meaning it only has that little bit of room when the springs lengthens over a pothole or something...
possible solution is to move the springs on a higher perch and thus give it more initial compression?? (might require a spring compressor).
--------
anyone agree/see some of these theories? any corrections? suggestions? other theories?

Most race springs are linear, but more harsh ride.
My H&R's are sport, (progressive) and I've never had the problem, but I have heard of it with some sport springs.

i took it to a friend's friend's shop and they said that the progressive spring rate of eibach is to blame. They said that it is quite common esp on accords where the body weighs a good amount. They said that as u go over big dips like the speed bump, the spring coils are so close together that they hit each other. That is why you cant hear them on small road bumps. I took off my wheel and placed the rubber sleeves on the coil a bit more closer to each other and it is kind of gone but still audible.
MY SOLUTION: go very slow on speedbumps. Then, i'll have no problems what so ever. Thanks all for helpin out and thanks to TYPE SH for bringing this issue up at H-T.com.

mines more of a rattling noise over road defects.

damn dude......i dunno about that. U should check if all the nuts and bolts are tight. ANy chance that the rattle can be coming from the interior?? i assumed that so i stripped my entire back interior, including seats, all carpeting, trunk materials, etc.

I had that problem until I transferred the spring silencers which were on the stock springs. Problem solved.
Only clunking comes from the control arm hitting the body when going over large bumps.

Yep, they are ion the stock springs. Kinda hard to see when your springs have been on the car for many years. The shop overlooked them. After I had clunking for one day, I looked at the stock springs carefully. You can see that there is some tubing which goes around the coils. They come off easily, and will fit on your aftermarket springs securely. I went back the very next day, and no more clunks ever again.
Now camber kit clunks are another issue...
