I had the same problem on my 98 lx I4 when I lowered it. The clanking was loud and very annoying. So i installed my stock ones back on and now it still makes that noise. I checked every part of the suspen. and I could find anything loose or what was causing the noise. It still makes that noise and it's kinda embarrasing when your driving by slow by people and they looking at your car while your car is clanking over bumps. I'm going to put my aftemarket springs back on and wrap them up but I know it wont solve the problem.
