I was driving and heard a flapping noise. Pulled over and saw a rip on the under carriage. Looked it up on the forum and wondered if anyone else experienced the same and knows how much it costs. Have an appointment coming up

Interesting this has happened to a few people. The same happened to me a couple weeks back. I didn't hit anything nor did anything impact the vehicle. I believe the bolt or whatever is fastening the tray to the car failed. I have an appointment at the Service Center on July 7.
They actually make a purple Loctite for vibration issues and it won’t stop the bolts from coming out like blue or red Loctite well…. But they definitely won’t vibrate looseI had the aero undertray on my Bolt damaged by deep snow two winters ago... yours looks like the bolts vibrated loose. I am replacing my MYP front undertray with an aluminum skid plate, and I will be using locktight on the bolts when I install it.

This isn't helpful. I've owned several cars, many of which were lower than my MYP, and never took on damage from road debris. As others have mentioned in this thread, no signs of or recall of impacting anything yet the undertray comes loose.Cars with a low ground clearance are prone to damage from road debris.
They do. I have them installed. No photos as it's basically impossible to take photos to show the full scope 2 inches from the surface when under the car on jack stands lol.I wonder if the aluminum guards cover as well as the plastic ones?
I went with the Mountain Pass Performance front unit because it is twice the thickness of the RPM Tesla unit. It does not have the acoustic foam, or nice black powder coat, but looks a lot more durable. I added my own sound dampening to avoid the large aluminum plate acting like a drum head... just installed it today so I don't have any real impressions of its durabilityThey do.

But they cover the areas the plastic ones did completely. Zero gaps or missing areas. Complete coverage. They may even extend a bit further, I should have taken photos or checked the aluminum ones on top of the plastic ones to see. RPM Tesla claims they protect the axels, which makes me think the "wings" may extend a bit further.
That being said, while aluminum certainly will hold up better to general road debris than the plastic ones will, it's definitely not thick enough, nor strong enough to straight up block underbody massive impacts like running over a tire on the freeway, massive rock, what have you.
They definitely won't get torn up by regular old gravel, rocks, regular road debris, etc, but they are definitely not off-roading level grade.
I have inspected my panels after putting a few thousand miles on them, and they have some minor scratch marks here and there, only digging into the powder coating. As aluminum won't rust, this is not an issue and is only cosmetic. No dents or anything, just minor scratching.
I chose this route due to my plastic ones being a bit torn up after not putting a ton of miles on them, and figured they would get torn up real good sooner than later, so I went with those RPM Tesla aluminum ones.
After taking off the plastic ones, it became obvious they are pathetically flimsy and weak and absolutely will get shredded long term. I'd almost consider them a wear part if you drive over bad roads with debris regularly.
Oh vey nice. Did you happen to lay the MPP plate over the stock plastic one to see if they were any difference in size? After looking at photos on MPP's website I can't help but think that my RPM ones cover more of the area, a bit of the control arms if I remember correctly, but I honestly can't remember.I went with the Mountain Pass Performance front unit because it is twice the thickness of the RPM Tesla unit.

Interesting data point on the stock plastic under tray... the two recessed nuts that screw onto threaded studs (back outside corners) were both loose! I was able to take them off with the socket and extension without using the ratchet.

You found you own answer on size, lets get into weight! The stock plastic panel is 10 lbs lighter than the MPP skid plate with a full covering of "kilmat" sound deadener. From everything I have read, I could have gotten almost as much sound prevention just by slapping on a couple sheets of the kilmat, but since I have a whole box of the stuff I went ahead and covered the whole panel.Oh vey nice.

EDIT: Actually I take it back. It doesn't, but it does seem like the RPM Tesla variant does cover more, not to mention having a rear cover available as well.
Was having trouble with the image uploader, but here are photos of them both installed:

Looks like RPMT claims "9 Pounds for Front and 10 Pounds for rear". Installing them, I'd say that's about on point. They also say "Stock Model 3 OEM fabric weighs 3 to 4 pounds" - I'm assuming this is the weight of the plastic for the front and rear *combined* as I still have mine and they weigh basically nothing.You found you own answer on size, lets get into weight!

PS: I will do an installation thread for the skid plate with some pictures later.

So around 15-16 pounds added.
Not particularly worried about it as I removed a lot of unsprung mass from my MYP by going from the Uberheavies to TSportline 19's, and all that extra weight is literally as low as it can get in the center of gravity on the car.
"They are made from 1/8" thick powder-coated aluminum along with 1/8" sound dampening urethane foam" - I'll bet your setup will provide way better protection (I mean MPP literally calls it the "smash me" panel lmao) and you are using a higher quality noise dampening product... so I think you have your front end better covered.
I wonder if they will come out with a rear panel as well at some point.
Looks like the MPP panel is 1/8" as well, so I wonder how much they would differ in terms of impact, if any.
I guess that means it's time for both of us to run over some logs and boulders in our cars and take one for the community. Whoever's front drive unit rips off the car first...
Lol
