Power to wieght is what we are talking about 30-50 lbs could be a 5-6 horsepower loss. I know you are going to laugh at 5-6 horsepower but hey you buy this type of car to squeeze everything you can out of it. In terms of horsepower, everything is about wieght.

It amazes me that people buy these cars and expecting for the money (in truth these are cheap sports cars) they pay to get everything in one package. There is an infiniti that boasts much of what you are looking for with the same engine and a back seat. Which seems a much more practical option for many of the complaints Ive seen an read about. I mean look at the Ferrari F40 (I am in no way comparing our car to it in any other way than it was also a production car), for the money you paid you know what you got? A/C.... No door handles, no carpet, no stereo *it did have an oil cooler " I dont know of any car designer who was designing a car built for speed and handling that would throw "cabin noise" high on the concern list.

I think you have to remember who a lot of your audience is here. Though there are some daily driver stock guys here, a lot of people here bought these cars to see what they could get out of them. A fun afforadable most bang for your buck sports car. So when you say people seem to think road noise is a positive issue, they arent they view it as an acceptable issue. I mean this isnt a personal attack, more of a defense of the people who dont mind the road noise. You said it yourself its easy to add, so if it bothers someone so much that they are having buyers remorse maybe a little more research or a few more test drives should of been on the menu.

My 2 cents, opinions are like @55holes, and all that jazz....
Perfectly stated.

I have said it before, and the 370Z is a GT. It should be comfortable on long cruises and the high noise level detracts from that substantially. And I don't mean big Lexus, BMW or Mercedes comfortable and quiet, but it could be much quieter than it is without affecting it's performance by enough that anyone who isn't tracking it at 9/10th's would ever know.
Nissan failed at something that was an easy design parameter. A 300 mile cruise would be much more fun if you could hear the stereo better and not have to practically yell to speak with your passenger, or yell to use the built in Bluetooth and have the person on the other end ask if you are driving a convertible with the top down.

Everyone in this thread bought one, nonetheless.
Nissan succeeded by saving themselves the expense of adding noise dampening materials and people still bought the car anyway. On top of that, they gave you the option to add it yourself if you so desired!

This thread is to talk about how to reduce the noise inside the car. If you're happy with the noise level, then fine. You're a happy camper. For those of us who aren't happy with the noise level, we're (many of us) are going to try to reduce it and we want to know all the techniques and info available to do so. If you don't think this car is noisy inside then this isn't the thread for you. Find another thread!

P.S. I just got finished with Dyanamatting the rear hatch area and also some Luxury Liner Pro over some key areas that sound like a tin drum when you tap on them. Noise level is definitely better. Not satisfied yet though. I plan to do the doors next.

When you do the doors you will really notice a difference. The installers were surprised to find NO sound dampening at all in the doors! I only wish I knew how do do this myself as I have the hatch, trunk and doors done and so far it has cost me $1200...and I would still like to do the floor..

That's what surprised me. Nissan put NO sound dampening on this car at all. I do understand what people are saying about "buy a sports car, be prepared for a lot of road noise", but with the technology of today, it's really not hard to get a great sports car that is also not unnecessarily burdened with tire noise and a cacophony of rock & pebble sounds. As a person that does track their vehicle from time to time, I can tell you that (imho) 30 lbs worth of sound dampening doesn't make a smack of difference. I challenge anyone to take their Z to the track and quantitatively differentiate the difference in performance between 3,330 lbs and 3.360 lbs. Take a decibel meter and you can differentiate between absolutely no sound dampening and 30 lbs worth of your favorite dampening material.

In for before and after dB readings from members' cars!
(anything else is subjective and anecdotal like measuring the effects of engine mods by buttometer)

I've said much the same thing in the past, unfortunately many people seem to take it as a personal insult that anyone could possibly find the Z lacking in any area whatsoever. Of course the idea of audio, engine, chassis or body upgrades to their cars is in no way offensive to them!

You are absolutely correct, if you can't make a positive contribution to the thread don't post.

This topic is relevant to my interests. Can you just buy some material and ask any body shop to put it in for you? Or do you have to find someone who specializes in sound-dampening? I'm not *too* bothered by cabin noise, but I certainly wouldn't turn down a chance to reduce it.

Just look up dynamatt on the internet and find a local dealer.. Its not difficult to install (except for klutzes like me!) but I would certainly never want someone who had never done it before to do it because once its down you can never remove it..

Sure thing there sport....When people post stuff like this, you cant expect people not to voice their opinion. If you dont want people to voice their opinions then this forum isnt the place for "you".

Actually, when I installed dynamat in the hatch, I noticed that there was some factory dampening already in place on the wheel wells. Several smallish patches on the interior of the hatch area (on a 2011 model).

You can save a lot of cash if you do the install yourself. I recommend Sound Deadening Materials for Noise Reduction from Second Skin and get the Damplifier pro and Luxury Liner pro. I've done the trunk and doors with this stuff and it makes a big difference when it comes to road noise.

The materials are pricey but installing yourself saves you in the end. You can probably do the trunk area and doors for less than $200 in materials. There's really nothing to it except taking apart the interior panels.

There's also the cheap way to suppress road noise. Go to Target or T. J. Maxx and buy a thick pilotes mat ($16.99).Take the cover out of the hatch, cut a pattern out of the mat using the cover as a guide (you might want to make the mat pattern a little larger than the cover). Tape it together on both sides with strapping tape and use small velcro squares to attach the mat to the cover. It doesn't eliminate road noise, but it does cut it bak to an acceptable level.
