Metal rattling noise
 

Hey guys was up, so I have my 2011 370z on swift lowering springs it has a 2 inch drop to it. Everytime I drive threw a patch of lose asphalt on the rode. I hear a noise coming from the front left tire. It's sounds like metal rattling in a plastic bottle. I checked everything out inspected every bolt possible and nothing was loose nor looks loose. The noise is only coming from the front left tire. Have any of you guys experience this noise before ?
