You are absolutely right! I am being picky, and if I can't make it any better I still am nuts about the Z. Just looking for ways to fix the one thing that would make the commute even better. I imagine Nissan went easy on the insulation to save weight, and I wouldn't mind giving up a few tenths of 0 to 60 time to subdue the road noise. I do like the exhaust and motor sounds, and if we could reduce the road noise, those sounds as well as the stock radio would be even better. Has anybody tried a different tire? Just curious. And I really do like the idea of taking the road less traveled!

I just installed 40 sqft of second skin's damplifier and 9 sqft of luxury liner (about 26 lbs total). The damplifier went in the doors, floor, and rear section and the luxury liner went in the back hatch area. The noise was significantly reduced, but not what I would call quiet. It has definitely increased my enjoyment of the car. If I had to do it again, I would have went with the damplifier pro and luxury liner pro and drop the sound a bit more. The extra 26 lbs was definitely worth it.

We are gettin gready to add a new package to our website specifically for 350/370z customers. 9 sq feet of Luxury Liner is not really enough to do much damage, but it will help in the specific area it is used. Our package is going to be something like: - 60 sq feet of Damplifier - 36 sq feet of Luxury Liner Pro This would make a very good impact on unwanted road, engine and exhaust noise and would add about 60 lbs or so. Always remember, there are 2 tupes of noise to focus on in any car. 1. structure borne noise - reduced with a vibration damper 2. airborne noisel. reduced with a noise barrier A combination of both products will reduce both types of noise. Another thing you can do that helps a lot is to use a vibration coating in the wheel wells. This is different from a rubberized undercoating (they do pretty m uch nothing for noise). There are a few companies that make good coatings: Quiet Car Stealth Kote Noise Killer We also make on called Spectrum These are acrylic coatings that dry to a very har, yet elastomeric finish. The absorb the vibrations and reduce the noise. Applying a 2 mm thick coating to the metal wheel wells and quarter panelos is a great way to kill the road noise. The closer you kill the noise to the source, the less noise will make it to your ears. Hope that helps! ANT Last edited by Second Skin; 01-08-2010 at 11:10 AM. |

In order to tartget specific type of noise you need to treat the area closest to the noise. Road noise is a bit more difficult than the rest, since there are 4 tires, placed on all 4 corners of the vehicle. I would start with 2 gallons of a good noise coating in the wheel wells and quart panels on the underside of the car Treat the sheet metal that surrounds the tires as well as inside the quarter panels if you can access them. Next, go for a vibration mat on top of the wheel wells in the hatch (inside the car)and under the hood. Under the hood might be difficult. Some cars only have a small amount of sheet metal exposed from the top of the wheel wells. Just do your best. Last, use a noise barrier inside the car on top of the vibration damper surrounding the wheel wells and quarter panels. You may have to do a bit of the trunk/hatch floor with the damper and the barrier becuase of the way the noise travels through the sheet metal. If you used our product you would go with something like Damplifier Pro or SPL Tiles (as the vibration mat) Spectrum (as your acoustical undercoating) Luxury Liner Pro (as your noise barrier) There are lots of good product out there, and I am obviously biased, being the owner of Second Skin so do your research and see what works for you. Our product can be expensive if you go with the better ones we offer, but you get what you pay for. We also have less expensive options for people looking to save some money as well. Again, look around. Whether you use Seocnd Skin or not, there are deals to be found if you do your homework. Hope that helps! ANT |
