I want to deaden the road noise in my 370z.

I'm thinking about going with this approach:

1) Cover the whole floor from firewall to trunk (including inside wheel wells) with Second Skin Damplifier Pro.

2 - maybe) I also thought about using Dynamat Xtreme, but want to keep my costs down (and Xtreme has eXtreme added costs). Originally I was thinking of covering every interior surface first with Xtreme (firewall to trunk, inside wheel wells, inside door panels, roof, etc). But maybe all that is not necessary for my purpose. Especially if I use the Second Skin.

For those that have used either or both, what are your thoughts? I'm hoping to keep expenses down, but still kill the road noise.




EDIT: Actually, I wanted to go with this, but grabbed the wrong links...
1) Luxury Liner Pro.
2) Maybe Damplifier Pro or Dynamat Xtreme.

damplifier pro is actually thicker than dynamat extreme, its definately a better value however you will be fine using regular damplifier, its close to dynamat extreme. I would also apply a layer of Luxury liner on the floor as well. That will keep eliminate more road noise than just the damplifier. The damplifier is mainly to eliminate resonance. that along with luxury liner would quiet the vehicle substantially. feel free to pm me any questions< i have tons of experience with both products.

I have used Rammat numerous times and find it superior to Dynamat and much cheaper. It doesent cut up your hands quite so bad and its more malible. It isnt as thick but a single layer is very effective and easy to apply and its thi9n enough that 2 layers where needed isnt total overkill.

I then apply ensolite, a thin foam fabric like material with spray adhesive and it absorbs even more noise. Its pretty cheap too.

I did this on my 04 dodge ram, did it for sound only but in this car where road noise is high I will be doing it for both!!

I ordered enough Second Skin Damplifier Pro & Luxury Liner Pro to cover my Z, and then some. I'll probably have this done beginning the 31st (too much work & such until then).

• 100% of the inside (minus windows) will be coved in Damplifier Pro.
• The floorboard & fender wells will be covered in Luxury Liner Pro.

Thanks much for all the advice, especially to Speedfreak28 who kindly took me under his wing via PMs.

Try to stay away from asphalt based tar-mats like FatMat. I have used FatMat before (50 sq. ft.) and it made my car smell horrible. It also melts in moderate temperatures. Dynamat is great, and I have used both the original and Xtreme with not much noticable difference. I would seriously recommend Second Skin. A great brand with amazing service. If you want some customer input, read here about Second Skin:

is accumat good?

I've come to acknowledge that road noise is just a characteristic of the 370z, all that padding is going to add weight

I went cheap and used peel and seal roofing repair.

No smells? How much was the roofing stuff compared to the dynomat stuff?

Wow. You might have found something here.

<experience>
Wait till your car hits 120* inside in the summer and you can't figure out how to get the smell/sludge out.
</experience>

Needless to say, that car got sold in December.

Have you determined how much weight gets added by adding dampers of any kind? I know that the spray kind is pretty heavy.

So how much quite did it get....

man your guna regret that.
