I think alot of you guys are taking the wrong approach here to reducing road noise thus not getting the desired results. Basically you've been falsely sold that lots and lots of vibration dampers will reduce noise. A vibration damper such as Dynamat/Raamat/Second Skin/etc only purpose is to control resonance in a vehicle’s panels NOT reduce noise. So don't expect to cover your entire vehicle in a vibration damper and expect to cut a noise. If you are wanting to reduce overall noise in the Z you are going to want to also add a close cell foam and a Mass Loaded Vinyl to really reduce noise in the car. To get best results you'll not only want to do the trunk but also the floor boards and doors with a Mass Loaded Vinyl. The Z comes with very little sound deadening material to begin with so applying 25% coverage with a vibration damper with a closed cell foam with a Mass Loaded Vinyl on top will reduce road noise in your Z. Companies like Second Skin and Dynamat do sell these MLV's but they are extremely expensive.
