<VV> Carpet Padding

[Bill Elliott]

I added a lot of additional insulation to my Corsa... here's what I used 
and what I found:

Stock engine lid insulation: likely the most effective sound reducer. I 
ended up not continuing to use it, but it was the single most effective 
piece.

Stock rear quarter insulation and then aftermarket 1" thick aftermarket 
insulation: could tell very little difference. BUT stuffing carpet 
insulation up into the quarters did help somewhat

Under the carpet I used the denser carpet pad from Home Depot and simply 
laid under the carpet. This was well worth the cost and effort... not so 
much in noise alone, but in overall feel. The issue is that you don't 
want that foam getting wet and retaining water for ages...

More effective (noise wise) was rolling up some of this pad and stuffing 
it under the rear seat.

Also, on the rear firewall, I used the silver backed 1" insulation (like 
from JC Whitney) covered with carpet vice cardboard. This seemed to make 
a difference as well, but not as much as the insulation rolled under the 
rear seat.

You'll never get a Corvair to the same noise levels as a modern car, but 
you can make it sound and feel more substantial and solid without much 
expense. But always beware of the moisture issues... and properly 
resealing the kick panels vents made almost as much noise difference on 
the highway as the carpet pad!
