Sound deadening/ride quality Options

[jmargush]

I built my car as an autoxer years ago and never installed carpet or sound deadener after the restoration.

Now as I age and have an opportunity to take a longer trip in the car I am looking for a little more "comfort" in the car.

Question is how much will carpet and/or sound deadening improve the road noise?

The back pad has been removed and there is sound deadener and felt covering the firewall currently.

Curious as to what you all might have experienced or recommend.


I am also thinking about dialing back the suspension setup for the long trip.

Coming back from Octeeener fest, MY 75 914 did not have the fire wall blanket, on on return I purchased and installed a Synthetic blanket from Rix914 at the show..EZ install and made a noticeable difference in the reduction of engine noise in the cabin. Wish I had done this upgrade earlier . Rick is a great guy to work with too

Does that mount inside the cabin ? Are they available on-line ?

It replaces the heavy tar/fiber mat inside the engine bay and is available online.

It's the same mat I went with and I really like it. I measured 1 dB sound reduction inside the cab compared with a less expensive sound/heat reduction mat. Unfortunately, I got too excited about installing the new mat and forgot to measure sound with no mat at all. It is significant though.
