Guard Dad
 

I have . Been helpful.

PM me if I can help.

Thanks Dad, I read through the entire thing now:excited:

Wear ear plugs .... lol!

So.. rebe let us know how your project turned out!

haha.. I just use the BOSE method...

Car is actually quieter than the 350Z....But still has noise...

will do
 

let you know when i drive her again.

The noise doesn't bother me. It's a sports car.

Or turn down your hearing aide:icon18:

Noise
 

You know, it never really occurred to me until I read about it. I have 18s so its fine. I mostly just cruise around so there is no noise. Yeh, over those concrete scored highways you hear some noise but never gave it a thought. Its a sports car. But I did insulate and will do the underside of the coroplast piece just underneath the carpet section and add more to the spare tire area to use up what i already bought. I also think a small thin:driving::driving: bed comfortor wrapped around the hatch area adds more. Those comfortors are insulated with a layer between the top and bottom. Or I may take the comfortor out and use a new piece of carpet insulation over the dynomat like product I used. thats it for me. I cant wait to drive it again. Maybe Thursday but Friday for sure since I scheduled an oil change. Im doin this because Ill be getting larger tires, possibly the 255/305 setup so This effort will not hurt.:driving:

Update
 

Cannot do the insulating on the underside of the coroplast. Its against nissans foam padding--no more room.so i just added the rest to the inner sidewalls around the spare and layered more on the bottom. We will see soon the results.

I turn up my music and if I'm not listening to music I roll down the windows to hear the VQ song.:tup: No rock noises for me.

Well i can now give a final report on the results of my efforts to tame this beast.

I have done the hatch and doors and the final thing was new Conti tires.. I am happy to report the car if perfect..for me. Its so quiet that I can actually see that any more sound dampening would spoil the sport car experience, as some have said.
Actually, i can also understand why some might think I had already gone too far...

...but I do like to take long distance drives with my wife and I just cannot bear the thought of the road noise drowning out her "helpful advice" as to traffic signs, my speed, braking, lane changing, other drivers and such..

Well i now feel I can really enjoy this car to its fullest...sometimes when driving on the back-roads, sometimes driving on the highway and always when ALONE..

This site saved me from what I thought was a huge mistake at first by buying a car that was just far too annoying on the open road...so one annoyance down...one more to go...if you catch my meaning..

Noise
 

Glad your happy. Im a perfectionist and i need to be satisfied in what I do also.
