Sound proofing experiment on the 370Z

370bluez · 09-14-2015, 12:41 PM

Final update.

Approximately 3-4 DB decrease from stock. The car is now decent in terms of road noise and you can easily hold a conversation with a passenger without feeling like you're in a club.

Total weight add was around 4-5lbs. Totally WORTH it mod in my mind.

No this car is not a VAULT as some like to describe these experiences. But it is certainly more livable and no longer a nuisance.

BlueZ, What is the name of that CCF FrostKing? I haven't been able to find it.
Thanks
I like the sound deadening spray idea. If we could just get a even application.

I would recommend going the same route as me and adding Dynamat around the wheel wheels since it adds an initial layer of mass damping. Even with those two layers in place there is still room for improvement in that area. There is a TON of noise coming from there from the factory.

That's for sure. I just returned from a 6 week, 6095 miles road trip.

I would think that would be good. Or something like a trunk liner in trucks for the inside wheel wells.
