Ok, i've looked alllllllllll over the place and have found the 2 cheapest materials: (((((((All materials INCLUDE S&H charges)))) E-Dead by Elemental Designs: -------43mil thick @ 60sq. ft. for $62.54 --------60mil thick @ 60sq. ft. for $83.97 Fatmat Extreme by Fatmat: --------45mil thick @ 100sq. ft. for $140.00 by all my calculations, Fatmat is the cheapest for the price... Has anyone use either of these brands? Any comments about these???? Thanks!

I would either use Cascade or Dynomat, except no substitutes. I have worked with other materials and actually did some studies on them for a acoustics class I took a few semesters ago. We set up several identical boxes and and used different damping material inside them to see how much SPL and resonations etc we prevented with each material. We found that no one came close to Cascade or Dynomat, we used E-dead and some others I cannot recall the names of them. It was a while ago, I would have to dig up my report and see what the brands were, but I do recall that they were significantly worse than Dynomat or Cascade. Good luck.

This stuff is all the same, Buy the cheapest that is appropriate to your application. The install is the most important thing. invest in a heat gun to heat the material and the surface it is sticking to. I like to put this stuff in on a hot day. I lay the sheets out on the hot pavement, and let them heat up that way. Saves time, and the material is heated more evenly than with a gun. Also use a roller and get it stuck down into all the "nooks and crannies" realy good.

I like to use Brown Bread. I have used all kinds of different deadeners and belive it has the best performance and price. 70 sq feet is about $155.00 shipped to your door. Here is b-quiet check them out https://www.b-quiet.com

I disagree that they are all they same, but whatever you guys want to do. The density of the material and the type of material that the dampning material is made out of makes a huge difference. I would look at the rating of density per cubic meter or whatever and compare those values, the manufacture will give them to you if it is not specified on the package. The goal ultimately is to decrease the amount of unwanted resonating frequency. It all depends on how much effect you really want and what type of results you are expecting from it. But the cheaper stuff is usually more difficult to work with as well. There are a lot of trade offs.

One other material to check out is Stinger's Road Kill. I have used that stuff for years and I feel it is interchangeable with Dynamat. I don't have a retail price off hand... i get it from a distributor.

Check out https://www.b-quiet.com Get the Brown Bread and a sheet or two of their L Comp. When used in conjunction with each other the results will amaze you. Used it in a Mustang Cobra with the same set up as you and it made it sound about stock.

Also instead of doing just the rear of the car I suggest you do the whole thing.
