I have been working on this since February for my Dec '23 Austin build LRMY. I decided to let Tesla try first and they did put on the hatch bumpers and a 'D' cross-sectioned rubber seal on each side of the hatch. I had to adjust the rubber hatch stops (envelope method) when I got home, but I did find it to be less boomy than stock - but not good enough. This weekend I decided to pull open the carpet and trim to have a look at the wheel arches. I was surprised to find a giant, ~10" cube of batting inserted over the driver side wheel arch. I didn't remove the sub-woofer so I don't know if there is a cube on that side.
The big surprise was 2" thick batting attached to the side carpet trim in the area that lines the side-bins. I can't tell for sure if the batting touches the flappy-vents that connect the cabin to the space behind the car's bumper, but it looks like there are marks on the material (see passenger side image) from the grid of the vent face. I took a drive with the two carpet side panels pulled into the middle of the car - it seemed quieter than when the carpet was installed in correct place.
Anyone else find this batting behind the carpet? I've never seen it in images or videos in this thread (
