Model Y Rear Spoiler, Advice

[bquinn2287]

I am looking for a rear spoiler for my 2021 Model Y. Unfortunately already have a couple paint chips from exposed area so looking at the spoiler to cover as well as prevent happening again. I'm looking for recommendation on best spoiler (basic matte or matching gloss black to car). In my research, I noticed there are wide range of prices but they all seem to be applied the same or similar as far as I can tell. My major concern is the spoiler delaminating or eventually starting to come off and I don't want to overspend on something that will not last. Appreciate any input.
Thanks, Brian

With a spoiler for the Model Y, you can give Tesla a more performance-oriented look that matches the sporty character of your car perfectly. What are the various aftermarket trunk spoilers you can use to improve the look of the Model Y, and which one best suits your needs in terms of aesthetics and material quality?
This blog will answer those questions. Plus, we'll tell you everything you need to know about installing a new Tesla Model Y aftermarket spoiler.

I don’t own a trunk spoiler but am looking to get one. Although I don’t have one I seem to believe that many of the ends raising or detaching has greatly to due with the installation. I would say 98% of YouTube trunk spoiler installs are wrong and horribly wrong. Peeling all the adhesive quickly then pushing down from the top only to talking about the bottom making a noise, peeling and unpeeling multiple times to get it to aligne, after cleaning the trunk touching and sliding hand on area that was just cleaned, etc. I look at these and wonder how many people follow them and get the same issue.

Now again I do not have one and can’t validate my theory. I do know that once you align your spoiler, you then begin peeling the adherís tails slowly as you continue to apply pressure as you peel along the way. Clean the area with alcohol and not touch the area with hands after cleaning. If you do the peeling as you press method you shouldn’t need to unstick the spoiler multiple times.

I am minutes away from buying the tesmanian trunk spoiler and trying this myself but with so many stories of it peeling on the ends it tough.

I am also tempted to buying the Tesla version for the warranty but would always wonder if I would have gotten similar results if I would have used proper installation on tesmanian carbon fiber version. Idk

If Tesla offer one together with fitting I would go for it.
On collection day, my Y went straight to a specialist firm for partial PPF and Ceramic.
I had purchased a Tesmanian matt spoiler for fitting at the specialist and was disappointed to find on collection that they had not been able to make it stick.
So, one unemployed expensive item ( shipping plus UK import duty) in the shed.
Good luck with yours if you go for one.

Every aftermarket vendor is selling the same piece, mostly made in China.
They may be using 3M tape, or they may have some 3rd party tape. 3M tape works well, others, spotty performance.

If Tesla will install and warranty their accessory spoiler, and you're unsure of doing the install yourself, then buy it from Tesla.

The spoliers are purely cosmetic, there's no other benefit than looks.
I have one purchased on Amazon for 85 bucks and it's been fine, DIY install, and I enjoy the look.

Wherever possibl; if they make it , I have purchased Tesla accessories but sadly,Telsla do not sell MY spoilers in the UK.

then it's DIY or have a reputable shop sell it and install it. I have no insight on any UK shop.
It's not difficult but is tedious to do right. check YT videos.

do NOT unstick and restick. it's one and done so get it right the first time.
3M tape requires 3 days curing time; hold in place temporarily with duct tape strips

I wonder how cars would look if function was the only criteria for their design; anything cosmetic did not make the final cut and there were no aftermarket dodads.
Even the Cyber Truck will have have a few nice to haves rather than need to have.
The first "go faster stripe" was probably attached to a model T when 3M were "minor" players

more like a raccoon tail. but yeah.
nothing wrong with cosmetic 'improvements'.

but fanbois many times get ahead of themselves and crave the best 'look' while justifying it as aiding performance.
witness low profile tires, suspension lowering, and body fairings.

For sure; some will always go to extremes. Interestingly though, the extremes, whether in car mods, or street fashion clothes, usually make it into the mainstream in a toned down form and become the common place accepted look ( for a while).
PS I now loathe very low profile tyres.

All the responses were centered around fit, which is very important, but is there any data on how many miles (70 mph baseline) is the range increased on a Model Y? 2" or 4" spoilers and of course CF is best for stiffness.

there is no range increase associated with a spoiler.
a spoiler provides more downforce at it's location on the chassis, in quest of providing improved traction
that of necessity is a function of aerodynamic drag.

spoilers on a Model Y are primarily cosmetic. they do not improve range, or improve traction for the most part.

spoilers wont stay on if the car has already been ceramic coated or ppf?

3M tape requires a clean, dry, clear coated surface. they usually supply an isopropol alcohol patch to prep the surface.
Ceramic would most certainly limit adhesion, and PPF likely too.
But why put PPF on the rear deck of the car?

was planning to ceramic coat my car as soon as i get it delivered...guess i should get the spoiler installed first before they start.

Correct. The guys who did my ceramic left a strip au naturale to stick the spoiler which didn't

Who did?

yes, thats what we usually recommend our buyers to do. otherwise the tape will loss over time.
and if the car is already ceramic coated, we would recommend owners use soap to wash the car, and then use alcohol to remove the coat on the install area.

Worked fine for me. I had Xpel PPF all over the entire car. I then applied two coats of Avalon King ceramic diy. The car is slippery as an eel and beads water excellently. And yet I was still able to stick on my Tesmanian spoiler with no problems. The only slightly loose section is the right edge that is lifted a bit because the curvature doesn’t quite match perfectly. Still hardly noticeable and I put some 3M adhesive tape there which didn’t quite fix the problem.

Sadly, that ship has sailed.

I need a video to show how to re-install a spoiler after it failed to hold first time.
This should include advice on the adhesive to use. If you run across one please let me know..
