Strange how things are..that pebble noise doesn't bother me ..its just what happens when you go over sand..and that is not very often..but that constant droning of the wheels on the road, especially with the sports package, is intolerable ...to me anyway..and its louder if the road is wet... depends a lot on the surface of the roads,..,on some there is no noise at all..others its .horrible.. At first i was sick thinking i had made a terrible mistake..

.. i had my car dynamatted..hatch and doors ..( there is no sound dampening material at all in either area) If you can do it yourself you save a lot of money...i spent $1200 when people tell me the materials are about $200..

but its ok now and i really love this car! but i want more..so in two months I am getting new tires...as the ones i have came with the car and I am told that they only go to about 20-25K and i hit 20 last week..

I think i will go with the Continental Extreme contact DWS...from what i read its a good performer and also good on water and snow and are much quieter..

Yeah, people are certainly different with their takes on this. Wow. Tire noise has never bothered me. Actually, to me it's something sports cars "should" have. I had one friend who loved it so much he never ever turned on his radio.

Anyway, not that you probably paid attention (since the incessant pebble banging doesn't bother you), but did the dynamat help at all with the sand/pebble/dirt noise?

Last night I decided to do a small little simple test. Using my hand I just started reaching under the car and knocking on it. What I found is the noise I am talking about is mostly coming from the rear wheel wells. When I rapped on those from the wheel side, the inside arches let out this loud tin like "plink." When pebbles hit it it sounds like a fully automatic BB-gun machine gun firing into the trunk. Not good.

So now I'm still thinking I should dynamat the wheel arches on the inside of the car now (while I have it all open), and then also paint the wheel wells on the outside of the car with rubberized coating to give it a more spongy/springy texture. I'm just still wondering if the dynamat might be a waste of time and money for the pebble noise.

Too bad Nissan couldn't charge us an extra $100 per car and have had plastic designed and produced for the wells. That would have eliminated most of the pebble noise I think, and also helped to isolate the road noise issue other have.

Thanks for anyone who can contribute to the dynamat helping or not with the pebble issue.
