you need something that is all butyl not a composite or butyl based that is a marketing tactic.

that deadner i listed is more expensive becuase it is a full butyl deadener.


also get something like 60-70mill thick the 80 mill damplifier pro with 4 mill foil takes some elbow grease to get it worked in there.
