Suspension noise

I recently replace the springs and struts to my 325 convertible(E46). The springs lowered the car 1 inch, it looks great and rides well, however I hear a clanking at low speeds.
Any idea why it would do that?
I appreciate any input.

shocks and bushings wear may be the reason.

Do you mean cluck? Like Metal to rubber? or more of a metal to metal clank? You only replaced the springs and struts right? When does it happen?

If it sounds more like a clunk and happens when you're coming to a stop its almost definitely your FCABs (Front Control Arm Bushings). If it's over bumps, it could be a number of things, but usually strut mounts or Sway bar bushings in my experience.

If it's more of a metal to metal clank it sounds to me like something was left loose... I'd check to make sure everything is nice and tight

I have the same problem on my 335i lowered into springs. Makes a clunking sounds when I turn the wheel all the way. Iíve changed tie rods so far with no effect.

I have discovered the problem! As it turns out the struts were not the correct ones for the lower springs.
I just went back to the original springs, and problem solved!
So, FYI, the struts and springs and shocks need to be pair correctly when replacing them.
