Cabin noise

Guard Dad · 05-04-2011, 09:29 PM

Has anyone done any sound deadening in the cabin area in the footwells and under the seats? What did you use and did it make a difference?

What's under the cockpit carpets anyway? Is it mostly bare sheet metal like the hatch area or has the factory put in any sound deadening?

I'm very interested to hear from the members on this issue.

I pulled up the factory carpeting on the driver's side to install some wiring, and as I recall, there is some kind of padding under the carpet. It's not glued to the sheet metal, and can be pulled up as well. Sorta like the padding under a regular carpet in your house? Probably provides some sound insulation too. Of course, this was a while ago that I did this so I might be totally wrong.

Calm down children, let's play nice. Behave and don't be the person at the back of the class that spoils it for the rest of us.

GuardDad- if you haven't already, check with 90ST. he's done a full dynamat on the car including floor board.

Guard Dad · 05-05-2011, 01:47 PM

I've already PM'd him twice and got no response, that's why I posted.

kenchan · 05-05-2011, 01:49 PM

hummm... ask him over in the audio section then?

Guard Dad · 05-05-2011, 01:55 PM

I'll give him another shout, maybe I screwed up, thanks

Hi everyone. Some months ago I mentioned that as part of of an audio upgrade I was going to add more sound deadener in the cockpit area, well I'm back to report the results.

As some of you know I've been aggressive in reducing the road noise in the Z. In the hatch I've applied generous amounts of Dynamat Extreme and covered most of it with Luxury Liner Pro. I've also applied Dynamat Extreme to the doors.

My most recent addition was to apply Rammat (essentially Dynamat Exterme from another supplier) on the bare metal of the cockpit floor. To do this I removed the seats and pulled the carpet back as far as possible. I was not able to apply Rammat to the top of the console and more than about 6-8" above the floor in the foot wells.

My observations are as follows:

Dynamat Exterme in the hatch and doors, approximately 38 square feet total: Huge improvement, modest cost, modest additional weight, modest degree of difficulty. Well worth the trouble.

Luxury Liner Pro in the hatch, approximately 20 square feet: Limited additional improvement over the Dynamat Extreme alone, this stuff is heavy. Probably not worth it unless the noise is a real issue for you.

Rammat on the cockpit floor, this requires removal of the seats, approximately 20 square feet: Rammat seems like a quality product but the improvement is this case was barely noticeable (the factory has already installed significant sound deadener on the cockpit floor) and is limited to a slight reduction of an annoying resonance from the foot wells that really wasn't noticeable until the application of the Dynamat Exterme and Luxury Liner Pro in the hatch. Probably not worth the trouble unless you are gutting the interior for some other reason.

The take away: Apply Dynamat Exterme or Rammat to the doors and hatch for a big noise reduction and only do more if you really feel the need.

Wow... so how much weight gain are we talking about???

By hatch do you mean boot?

In the U.S. the cargo area in a Z coupe is commonly referred to as the hatch and in the roadster it's usually called the trunk so take your pick as to which one would apply in your case. I have accumulated a fair amount of experience with the coupe but haven't done any work on a roadster although much of what I've learned should apply to the roadster as well. I'd be happy to share what I've learned if that would be of any value to you, just let me know.

ha ha , bloody americans! always getting things mixed up

Ive organised to have my doors done with dynamat extreme and the "hatch" area done with dynamat extreme then with Dynaliner on top.

Selected Dynaliner over Dynapad because it seemed pretty similar and it has a adhesive backing already on it.
