When I go over gravel or any kind of loose material, it sounds like a machine gun is going off. I'm sure it's loud in everyones car, have any owner's installed any type of insulation? in my opinion it seems to come from the wheel wells.

 

I've installed vb2 sound deadener to much of the car. Way Way quieter, but rocks kicking up are coming from the back wheel wells because there isn't the normal sub fender like the front. This is common on sports cars, but it would be nice if someone would make a sub fender for the back too. I would be interested in that. When it's wet out and my car has set, getting bits collecting around my back wheels, it kicks up a bunch until the Z kicks them all off. Normal but lame...

 

My road noise led to Nissan buying me to new front tires and realigning the front end. All done under the TSB identified on their Website.

 

Here are the details:
