SurfDog's Soundproffing journey

[SurfDog]

I Couldn't take the noise. I want to LOVE my Z, but the Friggin' road noise is killing me!!!

So... Dynamat!

Here are some Photos.
This one is about 1/3 the way into Dyna-carpeting my Hatch.

Here is the trim I pulled to get access.

Pulling the trim seemed a bit intimidating, but I spoke with my dealer service manager and he gave me some tips and advice (it was actually pretty easy)

Anyhow the results are noticeable but NOT A HOME RUN

I have ordered a 10 square foot FREE SAMPLE of GT Mat from Pintsized725. I will put it on the Doors as soon as I can find some time. I suspect 10 feet will *probably* only cover 1 door. We'll see.

My plan looks like this:
1. Dynamat hatch: done- result: noise is better, but not better enough.
2. GT Mat doors:Materials on order. Results-TBD
3. GT MAT or Dynamat Wheel Wells. Results-TBD
4. install quieter non-stock tires: I'll wait till my tread gives out: Results-TBD
5. Consider active noise cancelling sound system in cabin: Results-TBD

I'm looking for suggestions. So far my results have been a bit underwhelming.

The photo doesn't show it; I forgot to snap a "job done" photo (because I was beat), but I Dynamatted every inch I could reach of that Hatch and up into the left fender as far as I could reach. It improved, but DID NOT solve the problem.

If anybody has really nailed this problem down and can help me with "best bang for the buck" suggestions, please chime in. I don't need the Z to be silent, just pleasant to drive on longer trips.
