I agree with many in the forum who actually provide valuable info rather than opinions that sidetrack from the main point of the forum. You car, your money, your taste, your mods regardless of opposing opinions.

I too have found myself in situations where I was struggling to hold conversations in my nismo cruising at the normal 140mph (why I am talking at those speeds is not the issue, maybe I am being chased by zoombies in other sports cars, who knows

); I don't want to eliminate the sound from this sweet & mean engine since it is part of the awesome driving experience, I wouldn't mind reducing some of the slight road "noise/not noise/whatever all want to call it".

Would adding the dynamat to the doors & trunk suffice to eliminate much of the issue? Does one also need to do apply some dynamat to the floor for complete satisfaction ? I will be using the 20lbs dynamat 9 sheet pack.

You'll notice a difference for sure. You just have to go about it the right way.

I'm getting ready to add some noise reduction. One thing I've certainly noticed, is that the kind of roads you drive on make a HUGE difference. New smooth asphalt is actually pretty quiet.. stock. Any kind of pebbling or wear in the road surface accentuates the noise dramatically. For several extra pounds, I believe this will improve the driving experience for those longer times behind the wheel on the noisy road surface. Thanks to all for the great information.

I added some "Stinger Expert Roadkill" to the rear section of my car today. I watched the video on Youtube prior to starting the job, and had no problem at all. I added 20 sq. feet of the product and as directed by the video. The install was easy and all of the trim came out easily and went back in even easier. I took my Z for a test drive and immediately noticed a marked reduction in the noise from the hatch area. The same company makes a carpet pad that you slide under the carpet. I may try that next to quiet the front just a little.

WoZZer NAILED IT! I had dynamat (9 pack sheets) installed in my front doors and trunk. I did notice improvement over the stock (Don't ask me to quantify as it is very subjective but it was better than stock) BUT as WoZZer noted, the kind of roads you drive on DO make a difference. You'll still hear road noise if you are driving on non-smooth roads just not as more noticeable stock. On smoother roads, the noise is almost non-existent.

I had my audio upgrade done as well and will probably stop worrying about the remaining road noise at this level to avoid adding additional weight to the car. Overall, I'm satisfied with the Dynamat experience and would recommend as first step to reducing car road noise.

Your experience is consistent with that of many others on this site.

I too have noticed on some stretches the car is very quiet and on other stretches of pitted road the road noise jumps up to very high levels. The road doesn't have to be in bad shape to be loud, ...just the surface texture makes a big difference.

Yes this is what tells me the noise is coming from the tires against the road

I personally don't mind the noise, I guess I wasn't expecting it to be quite, thats why I bought the Z not the G

LunaZ · 01-24-2011, 09:47 AM

Quite, indeed!

I've read all the posts in this thread.... but not in one sitting.

So to my understanding, all 370z's have cabin "noise". Apparently it irritates some owners, and the others either don't mind it, or they don't notice it.

I have a question though, how does the general census rank the 2011 Z's in terms of "cabin noise"?

I test drove both a 2009 and a 2011... I didn't hear anything I would describe as "noise"... but then again, I did not drive it over multiple surfaces, nor do I think I drove it a long enough distance to encounter noise.

Can someone help me out with this?

Guard Dad · 02-05-2011, 09:05 PM

Can't say much about the 2011 as mine's a 2010. On my test drive I heard the noise but I was focused on so many issues (brakes, steering, transmission, seats, throttle response and more) on that brief test drive that the cabin noise issue didn't make much of an impression on me. It was only somewhat later that the noise began to be an issue for me. The noise is highly dependent upon the road surface, smooth road=quiet cabin, rough road=loud cabin.

Though I found the level of cabin noise annoying, I was never really worried about it because I knew that their were many affordable ways to address the issue. Dealing with it was just one additional way that I chose to personalized my car.

If anyone were to ask me, I would recommend the 370Z with enthusiasm. I would be candid though, and point out that the cabin may be a bit noisy for some, and anyone who intends to do a lot of aggressive driving will probably see high oil temperatures and, maybe, have brake issues. However, I would be quick to point out that all of these issues, should they even arise, can be easily and affordably addressed.

Half the noise due to the noisy stock tires. I just changed out the worn out stock tires with the Continental ExtremeContact DWS. The DWS tires are cheaper, much smoother & quieter than the stock tires. Now I enjoy my Z much more.

I just folded the rear seats down in my Mustang because I wanted more noise.
