that looks like a lot of trouble to go thru but to some it may be worth it, thx for the info.

I have found that the sti is incredibly noisy on crappy road surfaces only, surfaces such as that conglomerate (large pebble) old style of ashfault mostly found on backroads. On regular roads (95+% of road surfaces in this neck of the woods) the sti is not bad for noise IMO. I would probably suggest experimentation with different rubber before taking apart my new sti (less added weight too).

i used to work at a reasonably high-end car hi-fi place...

i recall that sometimes just a strip of that material, on the bigger body panels- like door shells, hood, etc. and make a noticable difference in the vibration. probably not a huge road-nise difference, as it will not help keep sound out.

but less vibration certainly could be a good thing. So, if you are already removing the door panels to put in speakers, why not consider sticking a thin piece of this stuff the length of your door?

Any of this type of material adds unnecessary weight. It is a tar composite after all. That is why there is a lack of such a material in cars such as the STi.

Mounting hardware

you are preaching to the choir here, my friend; you won't catch me doing this.

but, i could imagine many folks deciding it would be worth it to put a little strip of it in each door, especially if they are tweaky hi-fi types.

Me, i may not even install a radio...we can just sing songs & talk about our day!

:eek: :eek: :eek:

yeah that dynamat crap is really really heavy. Prolly take 100-200lbs of it to fill out yer STi. That is probably asking too much for most of us.

I would rather have the road noise, but then again, I don't think STi's are nearly that loud (my previous car was an 88 4runner so, :lol: )

well said, that is exactly what I was planning to be.. nice thin layer of isolation..
