maurim3 · 04-04-2012, 08:31 AM

Hey guys.. do you think this type of sound absorber would work ?

I would think any cloth like material would certainly help. Now add Dynamat or Fat Mat. The more = better.

Whatcha got there would probably help with high frequency sound control. Dynamat helps with panel vibrations. For total control you would probably also need something like Luxury Liner Pro, which is a closed cell foam bonded to a mass loaded vinyl, which helps control low frequency tones.

I thought I said that.

FYI did anyone read the recent edition of Car and Driver? They reviewed three cars..a Corvette, a Porshe Turbo and a Nissan R...One comment stood out..they said the R could have been the best for cross country driving ..were it not for the large amount of cabin noise..

I threw some pillows in the back today and tested the car.. I actually think it was a little bit better... but cant tell im just imagining it. I also dont know if pillows would be as effective as the sound absorber products out there. I think my car is extra loud cause of the tires. Im using some NANKANG NS-2 that came with the car when I bought it.

I had those same nankings on old lexus GS430, made that car rediculously noisy, can only imagine the tire size and a Z

I found this review about those tires..

These tyres are a genuine false economy!! They have decent grip in both wet and dry, but tyre noise got so bad I had 2 wheel bearings replaced before realosing it was the TYRES. Replaced with Pirelli P6000s and massive difference and not that much more expensive!

and in that same forum somone posted this..

I'm very satisfied with my NS2. I've used my first set for 4 years now, and will definitely consider buying them again, when it's time. They are silent running, and gives a precise feeling.

Enough to drive anyone crazy!

Some stores let you try the tires before buying and that is the best way to go..

Just changed out original tires on my '09 base for Continental Extreme Contact DWS. WOW! Cut out half the road noise and made for a less harsh ride, as well. Still a wonderful car---and now a joy to drive. Reasonably priced tires, worth their weight in gold!

I also changed tires recently to much larger Hankooks V12s 255/295. They're better than the smaller 225/245s 18s I had. Softer ride and noise is I believe quieter.

The Nitto Invos I put on the Z are significantly better IMO than the stock Bridgestone Potenzas. Less cabin noise, adequate handling, and way better wear performance thus far as well. My understanding is that the asymmetrical tread pattern on the Invos also helps to decrease road noise.

I am very interested to compare them to the Continental Extremes, but I've just been so happy with these Invos I'm not sure I'll switch.

The rear stock Potenzas were trashed in < 8K miles - the car is my wife's daily driver so this was unbelievably poor wear performance in my opinion. These tires are clearly garbage based on my experience and the accounts on this forum. Plus the dealer wanted like $375 per rear tire for 275s. I got Invo 285s at Discount Tire for $250 apiece! And we've already got more than 8K mile on the Invos with probably enough tread left for another ~4K miles (I believe these Invos start with more tread than is typical as well).

The best local shop where I live uses the Stinger Roadkill product instead of Dynamat. From what I could find on the web they are comparable products. Anyone have any experience or knowledge about the differences?

You would be good with either one. If you have a shop do it, make sure you inspect the coverage before they cover it back up so you are satisfied with what they do. I did my own, but if read this entire thread, some people got screwed.

Had the work done on the car today. They did the rear areas and the doors. I also changed the tires to Michelin Pilot A/S. Between all that there was a significant difference. I'm still going to have them do the cabin floor area, too, for whatever I get out of that. It was well done (I inspected it 3 times during the day), and they used 4 pkgs of the stuff (this shop uses the RoadKill equivalent to the Dynamat). I think I've gotten the most bang for the buck already, but figure I'm going to go ahead with the floor, too. It didn't make it quiet like some Mercedes, but I didn't expect that. Things are really improved and we can now hold a normal conversation even at freeway speeds.
