Elmz is San Deigo anywhere near San Diego? :)

Heres a thought,,,imagine if you were the chief designer and engineer for Nissan and they asked you to design the newest Z..now imagine if your goal was to read through all these postings and come up with a solution that that would please everyone!!

it works
 

Drove briefly , not a full test, but it really sounded totally as if in a normal sedan. Wow.

Haha! Man, I've been a member here since 09 and I've never noticed that :icon17:. Thanks! Updated.

1500 mile update -

The car is now as quiet as any of my other rides.
The new Yokohama S-Drive tires and doors/truck done in Dynomat extreme made all the difference.
No need to do anything else.

Moving on to do other mods... all done here. ;)

:iagree:

Looks like Dynamat will have to wait, I will be doing sway bars first instead, ha.

Dynamat is way overpriced for what it is. I have used B-Quiet and Secondskin. I just recently got done doing my wifes entire mustang in secondskin including spectrum, damp pro, and overkill pro. High quality stuff for a good price. Bquiet is really good stuff too not the quality that secondskin is but for the price its amazing. I will be doing the hatch on the Z here soon

So I did the Dynamat today. Definitely helped with the pebble noise, but maybe not as much as I had hoped. Did notice that the car has a much more 'solid' sound now though and you can definitely here the engine & exhaust more (even stock). One interior panel isn't fitting all the way so I think I've got a tight spot somewhere that not letting the panel sit flush. Figure I'll drive it for a while and maybe the panel will leave a mark on the Dynamat and I can find it.

Installed Frost king Duct Insulation today. It took a bit to do but once I figured out to work with larger pieces first it was easier. Many small pieces to cut though. Im wondering about the spare tire talk, I filled the rim with a couple old sweatshirts and want to pack some stuff in the 3 side slots around the spare.
I guess it sounded better but its tuff to tell with the AAM short tails:eek:

Cabin noise
 

Evil, what I did was apply the Frost King Insulation in many layers and added a 1/2 inch thick piece of backed on one side carpet insulation. I cut pieces to fit everywhere. the license plate section, the sides and even the section right behind the seats. I removed the spare( who needs it anyway). Then placed a folded bed comforter where the spare was.. Its clean and unseen. plus a nice storage area where the spare was. It definitely seemed to help, especially under normal cruising. When you first drive and listen, you maybe more aware and keen to any noise. When your driving later and not paying attention critically, you ( I) noticed a definite improvement. Thats enough to satisfy me. Now,as the other guys mentioned, you could get into the doors, but I dont want to screw with that and cause damage. Just add more and you'll see a difference. Plus, it cant hurt and doesnt cost much. I heard about second skin so maybe you could add more. Good driving man.

Oh yeah. Doing it sucks. 4 hours in a 'poop squat' putting the stupid stuff in. Having a little trouble standing up straight today. And I think if we had a contest for the ugliest Dynamat install, I would be hands down winner. Lots'o little pieces. Not a job for a perfectionist. After a while it was just do whatever I could to get the hell out of there.

My hamstrings are about to snap today:icon14: One thing I noticed now is how loud the doors are. Im not sure Im the guy to tackle that job. Is there some video here on how to do the doors?

Here's a couple of photos from my install...

Not difficult. If that were me, the Z would gain about 25# in sound insulation, noone would whine or bitch, and the stat would go un-publicized. Everyone would just notice the next model being much quieter and then they could opine on what it weighed, rip it out and weigh it if they wanted, etc., but 98% of them would just love the hell out of it and not ask.
