The dynapad took care of the rest of the drone for me. Certainly not looking for a limo ride, just reduce the bad noise from the road. Where I live they do alot of tar and chip road resurfacing, very rough surface which the Z amplifies.

Yes, under the carpet, on top of the coreplast. Very happy with the result. Wish I would have tried this before dynamat, might have been enough for me.
However, the combination of both has transformed my ride from what it was.

Yea, something thicker than dynomat. I saw dynomat, very thin. Im thinking 1/2 inch thick insulation under the carpet in the hatch area. Overall, road noise never was much an issue cause its a sports car anyway. But im lookin at larger tires and it may be more of a concern. Im going to Lowes to check out some insulating products.

This idea seems a fast and simple way to at least take a small but effective stab at some of the road noise. Of course further dynamat'ing etc would be more effective.. but if simply finding something thin and foamy to place under the hatch area carpet...makes a difference, I'm in. Please let us know your results!

Bought at Lowes today
 

A prouct called Frost king Duct Insulation. 12" wide 15ft long. Foil on one side and SELF ADHESIVE on the other . Thicker than Dynomat Extreme. Cost for 2 rolls equals 30ft long 12" wide=$40.45. I will let you know how it works and post pics. Says it insulates and STOPS vibrations. This will probably help since Im buying larger tires soon. Will do my hatch area . Looks exactly like Dynomat.

Thanks Rebe945..

even if it just takes the "road noise" on the hgwy down a bit.. a simple layer of insulation under the hatch area carpet mat.. that would be a inexpensive and simple solution...

looking forward to hear your thoughts on the results...

Done
 

Well, just finished installing the product I mentioned and I must admit , it looks good. Did the whole hatch area with overlaping . this product is thicker than Dynomat, self adhesive, has foil on one side . Took the comparment apart and simply cut sections and placed in place. Very good adhesion.Up on the sides where possible. Then I simply placed a small bed comforter underneath and around the spare. Earlier I drove with just the comforter and I noticed a definite improvement. If this works as I expect, no further work will be required. I dont want perfect quiet. It sound and felt very comfortable today earlier with just the comforter, so with the addition of todays work, should be fine. Will report back when I drive again since the Z is under cover and not a daily driver.

My return drive back from San Antonio to Dallas today was just great. The road noise was not bad at all. I drove over some dirt and rocks and only noticed the sound of large rocks hitting the inner wheel well with a good muffled sound. I guess my exhaust just needed the drive down to get broken in. It sounded great all day. I still have less than 800 miles on the car. I will not be using the dynamat on the doors at all. IMO, it sounds just right as is with the hatch and wheel wells dynamatted. On to the next mod (oil cooler).

No pics or vid on instal :pics:

Sorry man, I wanted to but I left my camera at my office. Will take shots in the near future.:mad:

How long did the whole thing take, did it require any special tools

Id say it took about 2 hrs total. It wasnt difficult .Lost some blood like others. Started earlier in the day then had an appointment . Came home and finished just before dark. Im also thinking now to do the underside of the coroplast as Scott In Indi mentioned. Have about half role left out of the 2 i started with. Walked the dog after that to cool off. Also just used good scisors. Again its called Frost King Duct Insulation .

I have had a 350Z and now the 370z..I know the road noise, but really......

Road noise ?? You want road noise ??

I will give you road noise...haha

The 370Z is silent in comparision...

I feel like my own "fast and furious " Movie....Am I dead ? In heaven ?
