Hello,
Has anyone used Dynamat on the inside firewall below the black base layer pad? If so, did it make a noticeable difference in noise reduction? Any suggestions for most effective use of this product? Thanks, Jack |

I have used this product on many projects. Makes a big difference. I would also put some in both trunks and under both trunk lids. Takes out the resonating tones. You will actually hear your engine with out all the static "buzzing".
The down side of course is weight, but if you are concerned about acoustics you are obviously not building a racer. You could take it a step further with a layer of of closed cell foam over the dynamat topped with a layer of mass load vinyl (MVL), but with the thin glass and frameless windows you probably wouldn't notice this extra effort Sometimes you can find a shop selling a package of scrap pices pretty cheap on eBay that you can fit together |
