I just jnstalled Koni Reds on my pre suspension upgrade (2021). Can't really tell the difference between the 2024 I drove for a couple hours.
Installation was on the easier side compared to the 15 others I've done. Took my time, 1.5 hours each for the front.
Tesla manual says no alignment needed, you don't really touch anything in the steering. Mine seems the same after.
There are a few one time use nuts you're supposed to replace. I used blue loctite, not too worried about it.
The pinch bolt on the upper A arm knuckle is a bit tricky, takes a bit of finagling to get it out.

You can see the part number of the rear strut by just looking through the wheel. Same with the front if you turn the wheel all the way to one side. Find it and then cross reference it. You should be able to google up the MYP part numbers. I believe the changes over the years are the last letter with F being when it switched to “comfort” suspension (but I could be wrong on the letter part). Your screenshot from Reddit shows an H. Also keep in mind that different factories may use different part #’s too.
I am currently running 39 on my factory 19's. Those are 255/45/19. Which modified size do you recommend for those?
Your post is the most informative one I got on this thread so far!
Would you be kind enough to give more details on the differences you felt after moving to Koni Reds?
Alignment,
That is what I thought, you are just replacing the shocks, not messing with the spring heights or other suspension components.
Those one-time-use nuts, Would anyone know what they are? what part numbers? I am guessing the back is super easy, it's the front that needs more time with the upper A-arms.
You can get the part numbers off of Tesla EPC catalog (just search the web and you’ll find it). They charged $0.50 a piece for the smaller ones and $1.00 a piece for the bigger ones.
I would also suggest getting some spares of the upper strut nuts in case you drop them into the abyss.

I try not to write war and peace, and in doing so miss-set your expectation. To be more clear:
1) Pursing replacement shocks on a '23 or newer 3/Y is a direction with poor, if any, return in ride quality or cost.
2) Instead purchase 18" rims that are 7.5" or 8" wide. I suggest 245/55R, and would look hard at the Conti DWS or the Michelin CC2. Of course I use all weather tires, you may not care. The newer Aero's, as an example, both meet payload and size requirements. Run them as low as you can and not have the TPMS drive you crazy. I'd look for 38, but your present 39 is OK too. Why Tesla doesn't make 18" an option is bewildering, for they fit all but they performance.
3) If I could find a TPS alternative, or setting for same n the car that allowed me to lower my alert to 34 PSI I'd run 36 day to day.
BTW, while tires that rate well for "ride quality" in reviews might be attractive, I suspect they get same from weaker sidewalls. Their is a point with which that's not good for an EV and it's torque delivery/weight profile. YMMV.

The Model 3 Photon wheels are 18X8.5J offset 38.
The Model Y Gemini wheels are 19X9.5J offset 45.
Would that swap work for comfort?
Hello,
I have installed UPP Luxury Suspension kit with their mild springs on my Y Performance from 2023 and I noticed a clunk noise while turning the wheel full turn which can be heard from outside (front left side) but is louder inside the cabin.
Have anyone encounter the same issue and how did you fix it?

I'm going to take a shot in the dark since I have yet to modify my Y's suspension, but I've had a similar sound on other cars in the past. Check for a loose end link, it's going to be really hard to tell while the car is on the ground and the suspension is under load.
So I come from a 2019 M3 lowered about 1.5" all around on MPP comfort coilovers with 19" signature wheels, square setup, same tire size as OEM. I find my 2024 MY on 19's way more comfortable than that. Even today, I road in a loaner 2023 M3P in the '20s and felt it was still more suitable than my 2019. I find it odd that there are so many complaints about suspension. Are your roads that much worse than Southern California? LA has some pretty horrific streets & freeways.
Hi, we double checked all nuts and links. not an issue from those. The noise does not appear all time and is not very loud. The seller told me to let the suspension settle a couple of days but I am not sure how it will went away just like that. I have also taken some picture of the front springs and to spirals which are very close to each other and there are clearly marks of ripped paint because are touching themselves.
Another big issue I have noticed: inside dampers box there was a manual for installation and setting up the adjustment knob where it was completely wrong.
On youtube, everyone are going counterclockwise being the softest position and from there you start the counting clockwise to desired position while the manual it was saying to go full clockwise and then count to desired position counterclockwise! I removed the rear dampers and pushed them down and youtube version was correct. This is a very unfortunate error from UPP.
Actually the manual was explaining in the exact way as adjustable Tein EnduraProplus which also are identical in term of psysical dimensions (!) which even UPP acknowledged that is true. Before this setup I had for 2 months the EnduraPro Plus with OEM springs (MY Performance 2023) and I was expected a more increase in confort but unfortunately I was dissapointed. The mild springs from UPP are smoothing out only very small bumps or small imperfections but going over potholes or speedbumps is worse than Tein combination with OEM springs and somewhat similar to original tesla suspension.
I wrote about all issues via support UPP email address but they are replying very slow or not at all!

See my face?2021 MYLR, dual motor, now at 52k miles.
MPP comfort coilovers, installed in 2021 at about 10k miles.
42k miles on the coilovers: no problems, no noises. Amazing improvement in ride quality, handling, etc.
YMMV.
I think the complaints vary so much because people are used to different levels of comfort based on what cars they drove previously. I have a 2024 MYP with stock 21” tires. I read so many complaints about the comfort level of this configuration that I almost did not buy it. But after driving it for a few weeks I find it to be very comfortable.
My previous car, which we still own, is a 2019 LR M3. That car is so rough on Southern California roads that I have to check and see if I still have all of my teeth after taking a long drive in it.
Before my M3 I drove a Lexus LS460. That car makes both of my Tesla vehicles feel like they forgot to put any suspension in at all.
when you adjust dampers you ALWAYS go full stiff and back off the same number of clicks. going to beyond full open can damage some dampers. The damping also starts to diverge the further you get from full closed.
Coils that close will contact and need some sort of rubber bumper or they will make noise.

Comparing a Lexus LS460 with a first generation Tesla M3LR makes no sense whatsoever. They are totally different classes of vehicle.
In my previous post you can see the indications seen on YouTube and also the manual instructions what I had in box with dampers. The manual was clearly wrong because I have pressed the upper mount to see in which position I have the faster rebound/compress.
Those coils definitely contact each other because the paint is ripped after only one day after installation as you can see in the pictures. Rubber band on them? Not a good idea when the coils are touching already while the car is stand still, the rubber will be torn apart immediately. In the rear are just fine also having some gap between coils and maybe on very big bumps will touch each other.
