Perspective..

I solved the problem of the excess noise ( to me anyway) with dynamat in the doors and hatch and increased the rear side visibility with small rectangular add ons to the side mirrors.. I now am totally in love with this car but I was thinking, its not at all unusual for people to modify their cars after they buy them.. how many have changed the sound system or even modified the engine( something I would never allow anyone to do, but just making a point) Others have changed the shocks or added something to the paint or put in a sunroof to their cars. ( i am not talking just about Z cars)

All this cannot make up for a basically unsound car but this car is great and I consider these changes to be individual customizations to make a good car great and a great car even greater! That is my perspective.

Visa
 

Just got a letter from VISA.. they have agreed with my claim and are withholding payment.. good reasons to use credit cards!! Thought you might want to to know..Meanwhile I love this car now and the noise issue is a thing of the past.. Rough start but very happy ending..

I think alot of you guys are taking the wrong approach here to reducing road noise thus not getting the desired results. Basically you've been falsely sold that lots and lots of vibration dampers will reduce noise. A vibration damper such as Dynamat/Raamat/Second Skin/etc only purpose is to control resonance in a vehicle’s panels NOT reduce noise. So don't expect to cover your entire vehicle in a vibration damper and expect to cut a noise. If you are wanting to reduce overall noise in the Z you are going to want to also add a close cell foam and a Mass Loaded Vinyl to really reduce noise in the car. To get best results you'll not only want to do the trunk but also the floor boards and doors with a Mass Loaded Vinyl. The Z comes with very little sound deadening material to begin with so applying 25% coverage with a vibration damper with a closed cell foam with a Mass Loaded Vinyl on top will reduce road noise in your Z. Companies like Second Skin and Dynamat do sell these MLV's but they are extremely expensive.

Yeah dont use the OEM tires, get new ones and try not to put heavy stuff in ur car

So bottom line I like my new Z sport package. But question is noise cabin or isit the bridgstones if so whats a quieter tire maybe Toyo are Hankok..

This thread astounds and amazes.

It is a sports car. Want noise? Come out to Sac and i will give you a ride in my 71 240. Want a nice quiet ride? Borrow your Mom's Camry.

I agree with you on that to some extent. Why buy a sports car if you want something quiet

I had a sports car. I bought a GT and it is a little too loud. Hearing very grain of sand from the tires is tiring after a while. OTOH, a little sound proofing or rubberizing the wheel wells would have helped a lot without too muc weight gain.

A sports car shouldn't need new pads, brake venting, and an oil cooler to track.

you only really need a oil cooler.

I tracked francorchamps spa the whole day and only oil temperature was a issue brakes seemed to hold up pretty well but I guess I wasnt fast and furious enough. :roflpuke2:

My understanding is better drivers don't heat brakes as badly, so maybe you were doing better than you thought! :)

I grow weary of posts that deal with the cabin noise issue with a curt "live with it". The forum is here to support its members with information about our favorite car, not to slam members because they don't share our exact same priorities for enjoying the 370Z.

For those who track the Z, brakes and oil temperatures are big issues. Since many of us don't tack the Z not everyone will share those concerns, but you don't see people telling the racers among us to "live with it" when it comes to fading brakes or high oil temperatures. On the contrary, people are eager to offer help and advice on how to alter that car to best address the needs of that particular owner. I think that it is fair to expect nothing less when it comes to cabin noise or any other Z related issue. If you can't post something helpful, perhaps you shouldn't post at all.

With the selective use of aftermarket products the Z can be a race car, a sports car or a luxury GT. I can't understand why the hardcore preformance types get so worked up when some among us would occasionally like to enjoy a little peace and quiet at the end of a long day.

On another matter, several times I have seen posts lecturing about the proper use of Dynamat and Mass Loaded Vinyl (MLV) soundeadner. By now most everyone knows that Dynamat is more for resonance and is not the ideal product for sound reduction and that it works best in conjunction with a MLV like Luxury Liner Pro or a similar product. Theory aside, I have used both products in the hatch area of my Z and I have to say that an application of Dynamat (about 85% coverage) made a BIG difference. The improvement form adding Luxury Liner Pro over the Dynamat was noticeable but not that big of a deal. I have posted liberally on this very thread about my experiences with both products.

What road noise?... Turn the stereo up? Roll the windows down? I got it....get an exhaust. :driving:

Yet another helpful post to turn up the radio, what insight!

That has been my experience too.. the car was far too noisy for me and my wife but an application of Dynamat in the hatch and doors made a huge difference. I am now planning to dynamat the wheel wells.
Dynamat saved me.,. I absolutely could not stand the loud noise. What was meant to be a pleasant fun trip for my wife and I and turned into a buzzsaw the very first day!!..but now that has changed:tup:. just in time for 18 inches of snow!!:shakes head:

I see you're from New England. I had Seamless Costom in Worcester put Lizard Skin coating all over the car. Much nicer ...
The real problem is the rear wheel wells and matting over that in the trunk and floors. They ring on course roads. The Lizard skid can be sprayed into the small supports in the wheel wells which you can't do with matting.

They also added some rear speakers at the same time. They smooth out the blast you get from having just front speakers. Nice job. Talk to Justin.

I have the base coupe with the sport package and base radio.

When the tires get old, I'll replace them with quieter ones. Thar should help as well.

Love the car....... Goodluck :-)
