Brother, Im not sure if Im gonna be able to make it to Columbia tomorrow, dude the inside of my S2000 is completely gutted, Im dead serious. Before I put everything together, I'd like to insulate the inside with the crapload of GTmat I just bought.

No worries bud. Just bring it up when you're finished. I'd be interested to see how it turns out.

eastwest2300 · 02-08-2013, 08:03 AM

Dude, the seats look amazing, I really thought it out before I installed the sensors, so I wouldnt have to go back and fix something, when Im done, its gonna look like a factory installed upgrade.

Dude... STOP

I thought you were going to bring the Z if the s2k wasn't done?

m4a1mustang · 02-08-2013, 08:28 AM

Dee and anyone else that is trying to use Dynamat/GTMat/Fatmat/etc...

This stuff is designed to dampen panel resonance. It's NOT an effective non-structure-borne sound absorption or dampening material. What it is good at is adding mass to a panel to change the resonant frequency and cut back on panel noise (structure-borne.) To do this effectively, you only need to cover 25% of a panel. You don't need to cover the entire panel as that's a complete waste.

If you want to block sound, you need closed cell foam and mass loaded vinyl. You place a layer of CCF on top of the panel to act as a decoupler for the layer of MLV you add on top. THAT is what blocks sound effectively.

This is a great resource for effective and efficient sound deadening: http://www.sounddeadenershowdown.com/cgi-bin/index.cgi

So if I just wanted to stop exhaust resonance from causing rattles inside the door/hatch/cabin, I should not do this you say??

Interesting read - so when I install my GTmat, I should only cover 1/4 of the trunk panel area?

The first step would be to cover 25% of the surface area of your interior panels with a dampening tile like Dynamat. That will reduce the interior panel resonance and be as effective as covering the entire interior in Dynamat.

If you want to block sound, then you need to use the CCF and MLV.

I'm not worried about sound as I like hearing my exhaust, I'm just tired of hearing rattles I can't figure out where/what they are to fix.

Makes it sound like somethings wrong to people who ride along.

Exactly.

My feeling is that you guys are going to end up wanting to actually BLOCK some sound, in which case you'll need the CCF/MLV elements. Unfortunately this adds weight, and for maximum effect you really need to do the floor, tunnel, rear wall, and hatch.
