Dealer fix for road noise

LunaZ · 06-23-2010, 11:02 PM

It's totally a lack of insulation and sound deadening materials.
Spray some undercoating in the wheel wells, as mentioned above.

My wife's Mercedes has a material that resembles indoor/outdoor carpet in the wheel wells. Even a gravel road is quiet in her car!

my passenger went like... "WTF is that?" my answer? it's the "road experience" that comes packaged with the car!

I'm just dumbfounded that Nissan would roll this car out to the general public knowing the tremendous amount of noise that it generates in substandard roads, non-paved roads, and non-ideal weather conditions!

Time to get a G37S?

Ummmm it's a coupe... Your going to hear the water because your so close to the wheels this will happen in any 2 seaters. My friends s2000 is the same way. Just get good tires and your fine..

I too have been very disappointed with the road noise in my Z. However, our Z is a very affordable, very capable sports car. It is not a high end sedan with all kinds of road insulation. So at the end of the day, you have to come to grips with it. Either you love the Z, and you forgive its little imperfections or you change out of your jeans and into a skirt and buy yourself a nice, quiet, blend, uneventful, common, simple sedan and enjoy the silence! It's all good either way.

The road noise in the 370 isn't much louder than my E92 M3 was. So I do think that people blow this out of proportion a little.

I'm doing a audio install and added some sound deadening last week and that helped the noise of rocks and pebbles a little. I'd bet that if the car wore Michelin PS2's like the M3 does that it would be much more quite.

Tires are a HUGE part of the problem. These RE050A's are quiet on some road surfaces and roar on others. If you want a quiet tire look at the Hankook V12 Evos.....Whisper quiet on my GTI and on my buddy's 370..

Some people drive their Z in the rain?

I agree with the Hankook tires, we put them on our G35 before we got rid of it and they were great.
