I decided to install the trunk insulation mat today. Everything went well until... I went to reinstall the extra plastic trim piece that some model 3's are missing. These mats don't have the cutouts for it, or even marks where you could cut-out the sections yourself. So I'm left with a choice of removing a good section of it to clear the mounts, or fabricate a template and cut-out areas for them to go through. BTW, I added extra 3M Auto Trim tape in a few places to help it stick.

The manufacturer is making rev2 that will work with the garnish and cover the sides even better, based on our feedback.
No ETA, no updates since July.

And that is precisely what I did back then. Make sure to leave a little (very little) overlap
to tuck under the garnish. And to trim more material around the side ends of the garnish.

You didnt trim enough on the sides if they wont clip in. The center section has to be almost flush... once you are close, seat the sides and use the push clips to hold the garnish sides... then tuck the center under and use the rubber seal lip to finalize the hold in the center.

It didn't happen - I decided to just trim-off the mat until it just had enough overlap to tuck under the trim piece. But the addd thickness still interferes with the two plastic clips built into the trim.
What I did is to trim the cover very close, except for two "tabs" that basically hold the thing in place. The "tabs" are positioned roughly halfway between the push-pins at the ends and the area in the center with the clips, i.e. in the middle of the sections of the garnish where there are no clips. Since I had replaced the adhesive strips with Velcro, I was able to make some small adjustments back and forth until I was able to snap the garnish fully in. Here's the result:

I ordered one and just received it. Has anyone installed it yet? No instructions included but it fits under the garnish and push pins and there’s a baggie included with non self-tapping screws and tabs

As a data point, this weekend I was at a EV drive event and Tesla Warwick, RI had a Model 3 Performance on hand for test drives. I didnt get a chance to see the build date, but the trunk shelf did not have the shelf opening like the earlier cars had. It was a full sheet of steel like one of the pics further up showed.

@TrevP,

Trev does your P3D+ have the Trunk cutout/screen or is it solid? My P3D+ is a Sept ‘18 and HAS the cutout. Due to this I’m Leary to cover it with this mat. But hate the unfinished trunk. (I know I could either cover it or cut out the grill area).

I put one in mine. My car has the extra rear edge plastic trim, and these pads are cut to fit without that extra trim, so if yours has the trim you'll have to "trim" off a bit at the rear to allow the trim mounts to fit. Also, it comes with pretty thin attachment tape, so I added an extra layer of 3M 1/2" wide Auto Trim Tape (on those 2 long bumps), and added an extra piece of tape along the cross-brace.

I installed this liner/trim finally yesterday. Few things I did not like are:
1. The bolts given to hold the this carpet/insulation in place. Small plate with a bolt. Plate has go into a hole above deck and bolt holding it from bottom. Couple of locations, plate keep rotating. Finally tightened, but I am pretty sure same hassle to take it out. Wish they had given carpet grommets just like Tesla uses it.
2. There are gaps between the existing insulation/carpet and this one in several places. Wish the had covered those too.

Other than those two issue, I have not seen any issues with install. I did some enhancements for reducing sound.
Had Dynamat on hand from my previous install from another car. So added reinforcements for the top deck metal, knocking and checking, and applying Dynamat where it is buzzy/weak. It did improve overall to reduce vibrations. The metal surrounding the hole from Cabin to Trunk on rear deck is the weakest. Sheet metal Under deck speakers and around is also somewhat buzzy so I added some Dynamat there too.

In the back, I removed Tesla provided trim, and used this directly. I created couple of plastic brackets and re-used the clips from Tesla trim to hold the carpet in place. Contemplating to add more support at the back instead of using double sided tape.

Now, trunk looks finished and good. Not sure about if there is any sound difference. Have not drive the car yet. I am hoping it would add some insulation.

Looks nice, but it would drive me crazy seeing those areas where it's not covering the steel/primer. Wish the manufacturer could see these pictures and correct the pattern so it's cut a bit better to cover all the areas.

Mine was ordered directly from AliExpress , has no gaps at all, fits like a glow (cheaper but takes over 4 weeks to get it).

The feedback re gaps was raised to manufacturer in China back in June July.... crickets re ETA or rev2 except perhaps these newer AliExpress Rakuten Alibaba shipments.

Did anyone posting here recently read the thread?
