Fender Coating to reduce noise

JoeyD

My MazdaSpeed6 had a material that resembled the carpet used on speaker boxes in the fender wells. When I first noticed I thought it wouldn't last, but it did. I've been wondering if something like that would be a good solution on the Z.

Yeah, my Mini Cooper S has the same carpet like material in the fenderwells, I thought it was kind of cheap at firlst, but it does a good job, can't here any rocks hitting inside at all. Maybe some outdoor carpet at Home Depot will do the trick

I had my entire rear dynomatted and it helped a "little". You can still hear quite a bit of pebble action.

The inner rear wheel well already has a fairly thick soft rubberised coating. The plastic panel that is removable is bare hard plastic and in my opinion the culprit when it comes to the tink tink sound of rocks being pitched up against it. A real thick coat of the spray stuff on the outside of that plastic panel will help for that specific noise.
The road noise from the drone of the tires on certain pavement is more pronounced because of the steel drum effect of the rear hatch area.
In my opinion the only thing that is going to quiet that down is a triple layering of the B-Quiet sound deadning material covering every square inch of bare metal on the inside behind the seats.
Just pull out all the stuff back there and start laying down the sticky rubber. I'm thinking 100 sq ft will put enough sound capturing material back there to really do the job.

My RX-8 has this too and I wish Nissan would do something similar for the Z.
