For some context, I have a 2012 G37 Sport Coupe on IPL wheels with 15mm spacers all around.

When I hit rough patches in the road or even when hitting the little reflective lane dividers I hear this metal sounding rattle come from underneath the front of the car, like there's something lose. It must be the driver side wheel, brakes/rotors or even something else under the car that rattles. This has been going on for quite some time. I had to get new tires recently and got an alignment but the sound persists. No warning lights on my dashboard. No vibrations when driving or braking and the car drives perfectly straight. I wanted to see if anyone else has had this issue or if anyone knows what may be the source of the noise.

Thank you!

@Surfnazi thanks for the theory! It makes sense. I hope the repair isn't too costly. I'll talk to the dealer as well as a few local shops to get quotes.
