Does the sound really make you suffer that much? I think that's a little silly. Should be the least of your worries.

They don't like the sound, they are trying to fix it. What's the big deal? Maybe it wouldn't bother you, but it obviously bothers someone else *shrug*

B-Quiet sound deadening material

Yeah, my Mini Cooper S has the same carpet like material in the fenderwells, I thought it was kind of cheap at firlst, but it does a good job, can't here any rocks hitting inside at all. Maybe some outdoor carpet at Home Depot will do the trick

Actually it doesn't bother me that much, but what bothers me more is that I've had to explain to several people what that tinking, clicking sound is coming from the back. I've had at least 3 passengers comment on the sound. Most of the times its not that bad, but on certain streets, streets that I never even knew there was loose gravel, because I never heard it on my other 2 cars, is very pronounced on the 370z.
There is one particular street about 1/4 mile driving up to my work that it is really noticable, I've driven down this street literally thousands of times in my G35, Mini Cooper S & Armada and never knew there was any kind of loose gravel on the road until I traveled down it in the 370Z. Sounds like i'm being pelted by a sandstorm.
I know where it is coming from, there is one parking lot that needs to be re-paved, the cars and trucks that are leaving from there are just tracking it out onto the street.

On a good note, I went into work this morning and the rubber treatment that I did make it less noticeable, I'm going to say that it's about a 25% reduction in sound, but still not like any of the other cars that I drive, so just a bit more work to get it there.

Definitely interested in hearing the forum's solutions. When i get my car, i hope replacing the head unit and all the speakers will have my music bumping so loud and clear that i wont hear the gravel being kicked around my wheel wells...

Hey has anyone tried laying a sound deadener mat on the inside of the car. I would think that would cut down the road noise considerably. I will be doing that some time this week when I can get through the 2 feet of snow to my garage lol...il keep you guys posted.

I had my entire rear dynomatted and it helped a "little". You can still hear quite a bit of pebble action.

Just strip out the hatch area and use some dynamat on the wheel wells.

You can hear the noise we are talking about in this video:

Gang,

When you check out the video above, also check out the Back-up Camera that I don't believe the US gets..................

370er · 03-04-2009, 06:43 PM

wow I didn't realize it would be that noticeable but it is. That's a cool video. The back-up camera is a cool idea for this car.

The inner rear wheel well already has a fairly thick soft rubberised coating. The plastic panel that is removable is bare hard plastic and in my opinion the culprit when it comes to the tink tink sound of rocks being pitched up against it. A real thick coat of the spray stuff on the outside of that plastic panel will help for that specific noise.
The road noise from the drone of the tires on certain pavement is more pronounced because of the steel drum effect of the rear hatch area.
In my opinion the only thing that is going to quiet that down is a triple layering of the B-Quiet sound deadning material covering every square inch of bare metal on the inside behind the seats.
Just pull out all the stuff back there and start laying down the sticky rubber. I'm thinking 100 sq ft will put enough sound capturing material back there to really do the job.
