Those rebound numbers are probably set too firm for normal driving. In my experience anything 9 or lower number for rebound will cause the car to be too firm against rough road and especially upset (significant side-to-side impacts) on paver stone streets. The compression of 13 is fine and...

My May 2020 build had cloudy windows from the inside. I spent a lot of time thoroughly cleaning with good glass cleaners- Gyeon, Invisible Glass, McKee’s, clay bar and the haze was still present. Luckily this worked: McKee’s 2020 Cockpit Glass Cleaner It takes more effort as it applies as a...

initial recommended settings (from MPP Coilover Installation Instructions | Mountain Pass Performance): front 12/12 (compression/rebound turns from full stiff) rear 10/8 (compression/rebound turns from full stiff) I've been tinkering with my settings to strike a better daily-driving balance on...

I think you’ll like 10/9 in the rear, with 9 being rebound- turns from full stiff. That rear rebound adjustment seems to make the biggest impact in comfort and firmness, roll stability for this car.

@1QYKMY the 720S trying to drive straight on this video loses control on launching on the street, similar to your case A McLaren 720S crashing into an Audi R8 shows launch control is not idiot proof

Yes there was settling, posted this awhile back where my alignment numbers (original post-install alignment (current measurements) vs. new alignment @ 1000 miles (before measurements)) drifted and you'd assume should be the same without settling in effect. MountainPass Performance Comfort...

yes that appears to be the going rate around here.. keeping up in price with our housing market I guess :rolleyes: @Ruffles did DIY route

Thanks for the update and I agree with your thoughts. To reduce the floaty-ness, and get handling that’s significantly better than stock Performance, try these settings especially as the shocks get more miles and become even better: front 12/12 (compression/rebound turns from full stiff) rear...

14 turns from full stiff on all adjustments would be the setting for maximizing comfort. Each of the dampers have different manufacturing tolerances (oil valving.. like your yard faucet) so while the 14 turns is what to aim for, you might not quite get there. You’ll likely feel hard...

I applied some butyl to the inside of the front fenders also, for areas I could reach, did about 50% coverage so as not to add excess weight to the car; tapping the outside of the front fenders sounds much more solid.. not sure how much of this noise translates or can be heard to the interior...

It comes in sheets with very strong adhesive. No tools necessary to apply except to trim with scissors but good idea to degrease/clean the surface, unless applying on top of the butyl layer; I’m a avid car detailer and use Gyeon Prep (essentially isopropyl alcohol surface prep) before applying...

I personally would not go as far as taking out the rear seats (and asking Tesla Service to do it will likely involve them putting in a permanent note on your car's history that this operation was done and will haunt you re: warranty / resale). If you have bothersome rattling from the car's...

While possible to remove the PE foam, it will be messy, similar to removing any foam tape which may easily shred the foam while leaving the adhesive backing on the surface. With enough effort and Goo Gone, it should come off completely. The butyl tape once cured may be very difficult to remove...

Do you by chance use an Apple Watch? It could be your sleeve turning the watch knob which controls the volume. The AW switches to the Music app automatically when playback starts in the car.

If you remove the back panel from the middle seat with your hands (the yellow clips), you'll be able to inspect whatever is making contact by pounding the headrest. To fully remove the panel, you'll also need to separate the top handle with a plastic trim removal tool which actuates the seat...

Rinse it off gently under the faucet and see how much has lifted. If it’s just the small corner portion, it would make more sense to reduce product waste by trimming it with sharp scissors and while doing so, round it off and you’ll forget there was ever an issue. The small corner area should...

I have the 21” Michelin PS AS4 tires and Mountainpass Adjustable Comfort Coilovers, rpmtesla noise deduction kit with extra sealing added to hatch (will address a lot of boom). The most significant fix for all the road noise has been applying butyl and foam sound deadener inside the front wheel...

Road vibrations and impacts which generate transmitted energy and resonance into the cabin, and may also rattle cabin bits like child seats, seat belt adjusters, dash panels, hatch, etc. are reduced, especially so on the softer MPP settings. Any suspension change will not help road noise from...

While I can count the number of times my wife has mentioned the ride being bumpy (I know she's avoiding hurting my feelings on this car), prior to the MPP coilovers, it was the net effect of increased anxiety I noticed on everyone after riding in the car while I drove in the same relaxed pace as...

The windshield washer filler neck can twist for easier access. MountainPass Performance Comfort Coilovers For access to front bottom adjustment, turn steering wheel all the way to one side and you’ll be able to reach it by lying with your back on the ground and reaching with your arm. You’ll...

I had a good local shop do the suspension install, but there are owners who DIY’d it in the thread, also see impressions from @Vivelemond who really prioritized comfort and noise MountainPass Performance Comfort Coilovers without going into the driving performance benefits, road impacts are...

With good surface prep (alchohol wipes) should take about an hour and easy to do; watch the install video on rpm’s product page. I don’t think it absorbs bumps better, instead provides better sealing, and likely limits movement with the doors, hatch and hood. Noticeable road noise improvement-...

I came across this on other car forums with aftermarket adjustable KW suspension- do not use the maximum softness setting on any adjustment compression/rebound. Doing so will cause premature wear and failure. At the most, back out at least to the last full click on that adjustment. from...

I’ve tried to very soft 14/14 all-around, but there were more turns to go even softer: MountainPass Performance Comfort Coilovers I drive through Seattle occassionally and know I-5 near the city is bumpy and the local roads are jarring on stock suspension. You’ll be happy with the night-and-day...

for those that have this, any noise reduction improvement, especially in the low-frequency booming from the rear cargo area as you’d get with rigid parcel shelves as in the Model S? any newly-introduced noise like rattling?

The rpmtesla noise reduction kit is easier to apply, cheaper and gives immediate results, especially when supplemented with the additional rubber seals on the rear hatch but mostly helps on road noise, wind noise, and eliminating the rear hatch buffeting and hatch movement (assuming the hatch...

One kit is more than enough to cover the intended areas as per rpmtesla instructions, however to cover the hatch gaps, having a 2nd kit will do the job nicely; you’ll have lots of extra material

biggest unsealed gap on the rear triangle window after rpmtesla noise reduction kit: also added supplemental piece to top of hatch to seal against wind, being careful not to overlap on glass portion, to not risk glass failure hatch gaps have much-improved sealing added additional longer...

I looked closely at the VW ID.4 at a mall, particularly with how they’re sealing the hatch. There is soft, flexible rubber on the body side. I believe a Tesla service solution in China in an earlier post had something similar but was much thinner. I’ve done something similar to my Y which...

FYI AutoAnything has the new Elegant mats for 2020 MY (no 2021 yet) for $225 after the 15% off https://www.autoanything.com/floor-mats/3d-maxpider-elegant-floor-mats I prefer carpeted floor mats over all-weather ones and usually stick with the car’s original carpets and vacuum regularly. After...

hi fellow Washingtonians ;) there’s a long video on SUMA’s website for the Model 3 mirror that has them performing the mirror swap.. it’s so brief you’ll miss it as you skim through the video which is 95% doing scarier things to wire the turn signal function.. it takes just a few minutes to pry...

exactly what @dfwatt described.. you can pretty much dial-in the MPP coilovers to your exact liking (firm -> soft, and anywhere in between) and get the right amount of handling and/or comfort balance.. at about 12/10 rear the passenger ride comfort on the 21" wheels is miles better than stock...

SUMA mirrors make a great improvement; if you have white interior and tinted windows, I recommend getting the non-blue mirrors to not have excess glare Posted to Reddit a while ago Model Y mirror replacement

apply as much downward pressure on it as you’re torquing it down; there’s a few mm of play but every bit helps to ensure the hatch is as firmly held against the body of the car to reduce any movement if hatch has trouble closing/catching, I would recommend applying lubricant to the catch such...

@52 16 57 39 not sure if you posted this elsewhere before- what rear camber numbers were you getting before the MPP camber arms after the spring drop? What will you set it to at the alignment shop? Also curious to see what sort of rear tire wear you were getting.

Got alignment done after ~1000 miles at Tru-Line Bellevue, who also installed my suspension, corner-balanced, and did post-install initial alignment and recommended I come back at 1K miles. Great experience as always. Inside of rear tire on both sides were showing heavier wear than rest of...

Happy springtime! Used my favorite portrait lens on my sloped driveway

Great and thorough post! One observation I had for the butyl tape is it appears to take many hours, likely overnight for it to become hardened and sort of fuse with the surface, and make a real improvement. When I applied it to my rear hatch and foam above it, I went for a drive and hardly...

@z335is you should see the thread Rear door paint chips/road rash poll it seems blue (as mine is) is most visibly affected by unprotected rocker panels (the painted bottom portion of doors); at minimum get the Tesla rear door PPF applied ASAP or have more comprehensive PPF on the rear door

I can't speak to its impact when you sell/trade. That's likely your best route if you choose to keep the car. It might be an upsell for a private sale. On the other hand, removing a full wrap involves long hours of labor, and could peel off paint (early Model Ys had paint peeling issues...

That makes me feel better that it's not a newer build.. at the same time I'm disappointed that Tesla had kept this car for a year surely knowing of the defect and why the car was rejected/returned and never bothered to fix it. Tesla recently started selling used Model Y and I always wondered...

@mnca what VIN range is your car? Also date of manufacture (on your driver’s door jamb sticker)? If March-April 2020, there were plenty of white and blue MYs that came out with serious paint issues- I got this info from service advisor who worked on mine. I think you can call this batch of cars...

I had rock damage but on the corner of my windshield, similar non-visible corner as yours. Used this rock chip repair kit Rain-X windshield repair kit and it’s hard to spot unless using a flashlight; if you use this soon enough before the crack grows it should work well. before: now (3 months...

I realized today one unexpected benefit of lowering the Y is much-improved rear trunk opening, at least for my garage (standard height for new construction- 7' 3" in my case). I think mine is lowered about 1.1" from factory MYP height, but due to design of car's hatch, I was able to raise the...

I only have the coilovers and adjustable rear camber arms which is really all Jesse @MountainPass recommends for non-track use.

those numbers don’t look good, at least compared to the alignment numbers performed on mine during initial alignment after MPP install (I have followup alignment in a few weeks).. those front camber numbers look off the specified range too

@MountainPass, I was just going through my photos (MountainPass Performance Comfort Coilovers) and others on this thread; it looks like our Model Y coilovers don't have stickers with R or L designations.. simply "870 1006"
