Hi, what’s the best sound deadening to use in the cabin without adding to much weight?
Thanks
Thanks
If you are going the whole course you need another layer on top of the butyl mat, which mainly stops drumming, its the second layer you put down that cuts out the noise. This usually consists of a dense layered foam.
I agree with this on both counts. Do your research on sound deadening, the butyl sheets do not absorb road noise they remove panel vibration. Dodomat is a good 2nd layer for road noise, but it doesn’t shape too well on complex curves and the weight mounts up.I used Dodo Mat - a UK company that produces the butyl sound deadening and the dense foam layer. Worked well.
I would highly recommend removing the factory sound deadening as I found moisture had gotten in-between and caused some surface rust under there.
His car is incredibly refined by comparison to mine, that said he's now carrying a huge amount of extra weight as a consequence.
I've no experience with any of these materials so don't know how heavy it is. When we say "huge amount" are we talking 10-20kg or something in total?
Agree Woody that's what I'm doing.
My dash has never been out but now thinking it's got to come off since I've gone this far and the bulkhead is the worse area for heat and noise. Can of worms !
