Only the fronts, and do you replace your existing wheel arch covers, or add this to them?

It does not look like it fits very well so might go over the existing liners. Although they shouldn't need to. This will work to reduce road noise. Someone may have determined that rear liners don't do much.

There are also some trunk liners for the underside of the hat shelf that would probably make a difference.

I might just buy the rear one because it looks so much nicer than what it is now.

Just as a note it may affect bass from audio.

Good point. I'd probably cut a hole for the grill and then use a rubber trim seal to clean up the cut.

I don't think it will. Low frequency sound easily passes through thin materials. Remember that the subwoofer already sits behind the trunk liner in the Model 3. Bigger concern is probably proper HVAC airflow from the cabin to the exhaust flaps under the rear bumper. But this pad looks like it will sit half an inch or so away from the rear deck, so it will probably let air pass on the sides. If not you could cut some openings.

Those front wheel arches cover have a big opening and would not completely isolate from road noise,
I wonder if it would be simpler and more efficient to soundproof the the inside bottom of the car and the wheels arches
with some sound proof material like Dynamat

$86 bucks for ONE Matt?? I thought the price was steep for 2 Matt’s which the picture shows.....but if you read the description it says ONE Matt? That’s “LUDICROUS”!!!

Looks like it is 2 as there are a left and right with no option to choose if it is really a single pc. I think it is just a mistake by the seller, my guess anyway.

In the product title it says "Pair" so I am assuming that "Number of Pieces: 1" means 1 pair.

A 'cotton pad' by itself will do little or nothing to reduce road noise regardless of where it's placed. Any change you notice will almost certainly be a placebo. My 2c is to put the $ into a proven solution instead of wasting money on this pad.

Proper damping requires 1- a constraining layer (butyl), 2- a decoupling layer (ccf) and 3- a reflective barrier (MLV). Source: Dozens of posts/tests/results on DIYMA and other reputable forums over the years.

Start at the source > tires. If you can't find a set that meets your requirements in addition to low road noise (or that set is out of reach for some reason), you can easily do the first 2 layers using something such as the 36sq/ft box of Noico 80mil and the 170mil sticky back CCF (on Amazon for about $100 for both e.g. relatively cheap). The existing liner can also be used as the reflective barrier by spraying the back with several coats of plasti dip or rhino liner, etc..(also making it 100% reversible) But be aware this mod will add ~10lbs to the total sprung weight.

I have done this mod (both interior/exteior sides of the well) and TBH the results are negligible. My 3 is often whisper quiet but on the majority of roads, but things still sound like I'm at the back of a damn airplane over rougher roads.

The weight trade-off isn't negligible however, unless you offset that weight elsewhere (via forged wheels, etc.).

Anyway I'll post some pics the next time I pop a wheel for some reason to show you how I installed the 3-layer version.

So I rotated my tires today at 6000 miles, and got a good look at the wheel wells, and my front wheel well inner liner is plastic, while the rear wheel well is a fabric material like the under tray that has had sagging problems. So, this front liner is fabric. It might help to trap some sound that would transfer easily thru the plastic wheel well, but I'd say under $50 might be worth giving it a try. At the current price, I'll wait for someone else to try.

Professional soundproofing model 3P...... very small improvement.

Small difference, but noticeable especially on the smooth road, and frequency is different. Would have been nice to hear on a wet road, cause I would think the wheel arches would make more noise then.
