If you are into audio upgrades it's easy to add 20-40 pounds of speakers/subs and amps too.

At least with sound deadener the weight is low on the chassis.

20-40 lbs is nothing! I'm carrying around at least that much extra everyday around my waist. :ugh2:

Well my plan is to lose the weight from my waist to compensate for the added gear.

Having just mounted up a new set of tyres, I can say that there was definitely a lot of noise generated by the stock Potenzas that's not present with my new rubber.

Love the cabin noise in my Z! Makes me feel connected to the car.

In for pics when done :icon17: cool and cheap mod.

I was surprised to find no sound deadening at all in the doors.. I did the hatch and got limited dampening....but the doors made the big difference.

Its fine now but I really, really like quiet in the car as I go on long drives and sometimes my wife or I want to nap in the passenger seat..so when the tires wear out I am switching to Continental Extreme contacts..i have asked enough people and there seems to be good reason to believe these will also reduce the noise..

I really have come to believe that Nissan did not add sound dampening because they want to differentiate this car from the G35 and G 37 and cabin noise is one of the ways...

What did you buy?

I had positive results from doing the door & trunk area; there would have been even better results from doing the floor too but I didn't feel it was necessary.

Are you going to lose a bit on the performance side going with the continental Extreme contact? I have a set of Continental (not sure if it's the extreme ones) on my Altima and they do last a very long time.

I've noticed that tire condition and road type play a huge factor in cabin noise.

I recently replaced my rear tires. The car is a lot quieter.

While driving to/from Z Nationals in 2theextreme's car, there was a stretch of highway 20 where the road has an extremely rough surface. You can barely hear the passenger talking.

I'll likely never address the noise issue in my Z, but I can certainly see where people are coming from.

I thought I was the only one. Rep point for you. Lol. :)

I should have seen this coming! Don't expect a six pack.

go for the 'one-pack' - success! :ughdance:

I think a lot of the "cabin noise" controversy arrises from the intent of the driver. If you want an aggressive sports car that reinforces the sports car experience with every turn of the wheel the stock Z is your ticket. If you want a car that expresses it's aggressive side "on demand" a little sound deadener goes a long way.

That's simply awesome. One giant pack success :icon17:
