i have heard this used in the early model nissan skylines to increse raginity(i think thats the word) but they used it to stiffin it even more after a roll cage was installed it also brings the weight distrabution closer to the ground

You mean increase 'rigidity'

And putting foam in the frame rails is going to have a very minimal effect on the weight distribution

If you got your head outta your ass you would realize that the foam needed isn't your standard insulating foam.

With basic reading comprehension, it is possible to see that in the article posted, they suggest a Foamseal product. Although that might seem like a reasonable place to start looking for info, you were apparently oblivious to this.

Because you can't function on your own, I will give you a link that a regular person would have easily found. Whether you will be able to make anything out of this or not, I am not sure.

Ok, I guess I'll just stop asking. Not everyone is a construction worker...

[FJ40]

how do you know which foam to use?

This any good?

That is seriously hilarious.

Actually, to answer your question seriously, I think what would be most desirable would be some memory foam. It might be a pain to install, but the gains would surely be worth it.

It's a simple answer. I read the article and I see no foam like that at my local hardware store.

[xLibelle]

yeah, go a head and fill your car with that shit.

you obviously didnt read the article

We've had to part out/scrap 2 M3 shells due to products like this.
Entire shell rusted away due to holding water from the foam.

What brand foam did you use? Some foams repel water others absorb it.

Just a thought. Im going with the autopower roll bar.

M3fan its supposed to increase rigidity while only adding 10-20 pounds, and maybe quiet down the interior.

[Garageaholic]

what's the advantage? i'm still not seeing this

Isn't there a new Ford or GM truck SUV that is currently advertized as being "filled" with foam? It should work to had strength, and keep sheetmetal from resonating. But if we remembers Ford's old Aerostar minvan, it had foam-filled rocker panels that rotted within a couple of years. That was a major blow for whatever company made those minivans.

[PiercedE30]

or you could do some seam welding........

But some guys mainly autoX where a roll bar isn't necessary. I think this thing will add less than 20 pounds to the car while increasing rigidity dramatically.
