ACC carpet mass backing. Yes or no?

Hello, looking at ordering carpet for a 5 speed conversion on my Challenger. What do you guys think of the mass backing option? I thought I read somewhere that it was a pain to fit on a 4 speed car. This will be a non console car. What are your opinions on the mass backing? Thanks

I've used it in a couple vehicles and will buy it again. It's a huge help with noise. Only fitment problem was on an 80 Ramcharger and that may have been due to the changes in the floorpan in the early 80s. It seemed like the carpet would have fit my 85 better.

It's a rubber like material, and will possibly trap water under it. But so will jute.

Ordered it about a month or so ago for a 72 B-Body 4 speed with buckets and had plenty of extra material and it laid down to the couture of the floor perfectly.

ACC has a good rep for over the years, will be ordering for my 1972 Charger as they are top of the list off suppliers.

This is a vender for ACC at a better price.

Yep. I go to them first

I found rockauto.com to be the cheapest for ACC carpets. https://www.rockauto.com/en/catalog/dodge,1970,challenger,7.2l+440cid+v8,1495993,interior,flooring,1264

Essex carpet + mass backing: $296 at rockauto vs. $360 at stockinteriors.com

I would make sure they are both from the same maker before ordering one

Purpose of mass backing is ??


I just did the Fatmat / Dynomat type stuff on mine this past weekend.

Makes a noticeable difference for both noise and heat inside the car

Says ACC on the webpage and came in an ACC box...

The same. But it comes as a full size part of the molded carpet. And is much less expensive than matting.

I was so impressed with the first, I won't buy it without now.

this is a timely thread as i am ready to purchase carpet for my charger.
thank you guys for helping out with my decision !
