What is the crap in the trunk?

[Stevoyayaya3]

So I was messing with my e30 and noticed a little water in the trunk from all the rain we had. But I went to clean it up and it's a 87 and has what looks to be sound deadening material. I started to pry it up and noticed moisture trapped between it. It's like thick almost cardboard material. Any clues to what it is? I pulled most of it up.

You mean the black thick tar paper type stuff? Yes, that is sound deadening which is there to try to reduce some of the road noise.

Ya that stuff it think if I would have left that stuff in I wouldn't have a trunk lol. It's horrible.

Since it is only found on 6 cylinder RWD cars and weighs 57 lbs, it is safe to say it is for weight balance.

Also, it really does not have any effect on road noise. If it were for sound deadning, they would have done the spare tire well too.

Ya that makes sense. It's not in my 318is. But it's gone now and hopefully I can prevent anymore rust from forming lol

its all over the place on the floor of my 318is...although I've removed a bunch to fix rust holes

So you are saying you have a 4 cylinder with trunk tar?

Gotcha....no, this is about 3/4" thick, weighs 57 lbs...nothing like the floor stuff, this is thick!

I checked mine, and its not black - its white. Now im wondering if someone painted it.
