[str8304]

I have my car lowered and and now it make a noisy sound on right back passenger side? Does anyone elses car do this? If so what is it and what can I do to fix it?

Where is the noise? Is it coming from the suspension or from the metal inside the car? Pretty much ever sense I lowered my car, you can hear some creaking in the sheet metal behind the rear seat, but there isn't much you can do about that with such a stiff suspension. I just turn my stereo up and I can't hear a thing.
