Use Dynamat or not

bigaudiofanat

I got done an install yesterday actually part of it. It was a honda crv, the guy called me on the way home and told me the suv handled totally different, it was a lot heavier, seared harder, and did not accelerate as fast.

Now that was in a suv I can only imagine what it will do to a sports car like the Z.


To answer your question chibbell, look at my install thread and the other one that should give you an idea of how to install the stuff. Just take your time.

Did you ask him if he had that same problem whenever he has a passenger in his vehicle too? Not saying the added weight wouldn't cause a slight performance decrease, but "totally different", somehow I doubt that. In my RSX I had the entire thing sound deadened with two different types of material, one for road noise and another for sound quality, and didn't feel any noticeable difference in the way it handled. Granted, it was hardly a sports car, but still, I doubt added 40-50 lbs is going to be that big of a difference in acceleration. (In my completely uneducated opinion, of course )

Um we used over 4 boxes and we have not even gotten to the floor until today. Each box is about 50-80 pounds worth of dynamat. You start putting 50-80 pound boxes into a sports car it is going to handle differently.

A sports car would handle differently with an additional 200lbs, but an already pretty heavy SUV? I doubt that.

I also don't see a need to use THAT much Dynamat in the 370.

No matter what the car is I think additional weight will effect it.

I'm just saying that under most circumstances I think the effect will be minimal. Of course if you did add 200lbs throughout the Z, I think it would have an impact, but even then I don't think it would be too noticeable unless you are tracking the car. That said, the Z doesn't need 200lb's of sound deadener.

Sorry to pull this out from the dead, just took the Z on a road trip from Austin to Houston and there were certain roads where the noise levels were completely unbearable! I thought my hybrid was noisy because of the thin panels but the Z is VERY noisy on poor roads.

Good roads, it is very quiet, but the poor paven ones, the decibels are probably in the lower 90s+

So...I noticed that the rear of the car is particularly noisy, especially when raining. What other panels can I apply this to, to get rid of the road noise?

well my RE11's aren't THAT noisy so some road noise is fine in a sport car.

check with ms.pint. she use to sell GTMatt (i think it was called) and they were like a cheap replica of dynamat.
for me, dynamat only. why? not sure, thats wat ive always used.. lol

There are far better and cheaper options than Dynamat. The only reason people use Dynamat is marketing or blind brand loyalty. I used Raamat. Keep in mind, the Dynamat type product is only half of what you need. You also need to apply a thin layer of closed-cell foam over the dynamat to get it to really work. It's cheap and really makes a difference.

Okay, i'll start looking at the different options. Will keep you fellas posted!

I just got some new Continental DWs to replace the OEM Potenza's - supposedly they are quieter but I know the Z isn't known for its quietness :P

I love the current noise levels but when I am poor roads (could be often in houston) the noise is NOT bearable for long periods unless I used ear-plugs

those tires are actually pretty good. very compliant ride.

will make your sport car feel like a wimpy sedan.

Is anyone running the superlite?

Any difference in noise reduction?
