That's what I'm hoping for. I wish I had some way of measuring the sound levels. Anyone know of an iPhone App that works?

We'd like a photo showing most of the car with some install showing, but knowing the Z, that is a hard shot to even get. Any creative shots would be appreciated.

To get to the rear fenderwell, you need to take all the panels out of the trunk and then take off the panels behind the seats too....then you can add the sound deading material to the rear fenderwell on both sides. They are super easy to remove. The poster in here only added the material to the floor of the trunk. You need to do the whole thing....bottom and sides with fenderwells.

only thing i didn't hit was right above the wheels. Otherwise, i completed the majority of my trunk.

Update: I installed roughly 30-40 sq ft. Today in the doors and in the back. First impression is wow. It has made a huge improvement so far. I will have more gopro videos later with decibel readings. The smell is basically non-existent. I was installing outside and never really smelled anything.

I would highly recommend this to anyone. It's a cheaper option than some of the other brands, but works EXCELLENT.

I will be installing more under the carpet underneath the seats next week.

Huck · 08-17-2012, 02:09 PM

Alright, I'm typing this on the computer, and then I'll add the pics from my phone. I suck at reviews, but I'll give it my best shot.

Customer Service:
The man I spoke to on the phone was very courteous and friendly. I asked him a few questions and he explained the answers in detail for me. I have nothing bad to say about this

Shipping:
It shipped the same day I called them, and arrived 3 days later. Everything was packed well, and the box included the GTmat, instructions with pictures, 2 GTmat stickers, and even a little roller. I thought the roller was a nice touch, and it made the job a lot easier than smoothing it all with your hands. I would have gotten tired of that pretty quickly. There was also a coupon in the box, if you like the product and you want to get some more then you can save $10 (I think that's what it was). Very pleased so far

Quality / Install:
I have to admit that I haven't had much experience with sound deadening material before, so I'm kind of a noob with this. But this stuff looks to be pretty good quality. It's got a little weight to it, but not too heavy. The adhesive side stuck well to the truck of the car and once on there was actually difficult to pull back off. It was my first time installing this kind of stuff so I honestly don't know if I did a good job, but I gave it my best. Feel free to critique my pics. The install seemed pretty straight forward, the stuff was pretty pliable and wasn't a PITA at all. I also heard people asking if there was a smell to it. This may sound stupid but I actually stuck it to my nose and didn't smell anything. Then, the next morning after the install I went back into my car and did a smell test. Nothing. I asked my wife to check it out. Nothing. Happy about this as well

Result:
Just with the 10sqft I can there's a noticeable difference. My exhaust is a little quieter, and the road noise is a little bit lower. I would think that if you got enough of the 80mil to do the whole trunk and the doors (50sqft?) sound would be reduced dramatically. I have also noticed slightly better bass response from my 12" Zenclosure in the back. I took a db measurment before I did this, but I haven't gotten to take one after so I don't know how the numbers have been affected. I'll probably be able to do that this sunday, then I'll post it up.

All in all for the money I believe this is a great product and a great value, and as soon as I get my components I'm going to be giving these guys a call back for some more of the 80mil. Thanks GTmat!

EDIT: on my phone now, here's the pics I took with my iPhone

I'll head over there a little layer

Just got my sample today, will try to install and get a vid produced by the end of the weekend

Nut_N_Much · 08-18-2012, 05:30 PM

This is what I used to sound deaden my Sophie

. I ordered off ebay 50 Sq Ft, it came in the mail with in 5 days. Came with the roller and some plastic tools to smooth it all out. I laid it from the Fire Wall all the way back to the trunk. Also did the roof, worked awesome. I have ART Test Pipes on Fast Intentions Carbon Fiber Exhaust cans (Loud inside cab)... After deadening I could talk on the blue tooth with out yelling.

The 50 foot roll was around 25 pounds. I put it on a scale before laying it out. My trunk had been done already by someone else but there were lots of gaps, and surface areas not covered. I laid G-Matt over it and used sound deadening spray to get in areas that are hard to reach. Makes a big difference. Once I finished I went over it all with a heat gun, made it more pliable and formed around tight corners and difficult areas.

Thanks G-Matt, if you come up with any new stuff, I'll test it for you !!!!
