i installed a tein basic coilover system on my 04 3s two weeks ago, and ive been hearing this noise that kind of sounds like an old creaky door thatd be on a haunted house or something...this noise only occurs at low speeds (15mph or less), from inside the car it sounds like its coming from the front right of the car, but when outside the vehicle the noise comes from the rear right side. the noise only happens when im turning the wheel. my car still drives and handles top-notch, but the noise is a bit unnerving. so far ive been able to figure out the noise isnt cause by tires rubbing against anything, and its not the shocks...

any idea what this could be, and should i worry about it

 

I'd use a WD-40 type spray and try to figure out where the noise is coming from. Do only 1 connection at a time (any bolts you loosened/tightened are suspect) and hose it down and take a test drive. Once the noise is gone, you know it was the last fastener you hit (unless it just to awhile for the penetrant to get in there.)

Not sure if your coil-over set-up has a specific orientation for the coil, you may want to check that as well.

 

thanks.
