Performance spoiler coming off
- Thread starter Tann_man
- Start date
I have the spoiler in my closet and I don't put it on because of all these posts about it coming off. Also I am not sure I like the way it looks.
Anyway, has anybody tried to solve this issue themselves? Why not silicone the corners on or use a glass adhesive? My previous vehicle had a recall for a front hood cowling that could come off. The recall called for it to be removed, cleaned and then this beta seal adhesive was applied. It never budged in 10 years after. I am pretty sure glass adhesive can be removed though since they cut it out when you break a windshield.

Remove it using a little heat action while ‘sawing’ with 15 lb (ish) fishing line... hold the ends of the line away from the car.
Remove the adhesive by slowly rub / rolling with your fingers. Be meticulous here and final clean with alcohol.
There are 2 locator horns to help setup final placement (at least on the MY)
Use 3M molding tape... I used 1/2 and 7/8 Carefully trim the ends to ensure the tape is not touching the edge... I used a fresh exacting blade.
The curve is exact and extreme care is needed for proper placement. Dry fit to find the best match for lay down and mark the ends with tape as a guide.
remove tape from one of the guide horns and position... press firmly at the horn for transfer. If good repeat with the second alignment horn.
Remove all the tape and slowly mate the spoiler using the guide horns until it just kisses the car... firmly work from the center to the ends.
As good as it can be done but it takes some time and an extra set of hands during fitting is helpful.

There are no guide pins on the 3.
I put my spoiler on with the below tape and adhesive promoter (it held with amazing strength instantly) but i didn't like that there was a slight gap maybe a 1mm between the car and spoiler in places. I feel like water runs off the trunk and works it's way into the spoiler adhesive so eventually the corners give.
I put silicone around the top edge and corner. The bottom I left open. It's hard to see in the pictures because the bead is flush or slightly under the spoiler. I taped it off and spread it out. Then just took a paper towel and my finger nail to make the bead under or flush. The silicone is easy to wipe off the trunk before it's dry. It comes up with paper towel. After it's dry you can peel it off if you want.
There is no movement of my corners at all now. Time will tell how long this holds but it's been about a month already.

Surface prep is vitally important to ensure they stick at the ends. So if you're putting the original one back on you must get rid of all the adhesive residue on the spoiler then clean it and the boot lid with IPA (not the beer!) then apply VHB tape to the spoiler (genuine 3M, not a cheap knock-off tape) then use adhesion promoter on the boot lid and when and you've done all that you can stick it on and keep pressure on it all the way along for several minutes if possible (boring, but it will help it to bond).
If the weather is cool, warming the boot lid with a hot air gun first will also help.

Just improve the look of your car by taking it off?
Kind of joking there. If mine does the same I'll be happy. As ugly and unnecessary as the spoiler is, given it's part of the car I'd be unhappy if it just came off. I'd also be in the service centre to fix it. Don't see why I should DIY fix something that is a warranty fault.

Tesla removed my spoiler shortly after delivery in August last year: Model 3 Spoiler
I just don't like spoilers and the performance one is particularly bad fitting and unecessary, Also my wife always closed the boot with it so that probably didn't help
Looks much better without I think

Mine’s coming away on one corner now, pretty much the same as the OP’s photos. Other side seems fine, for now.
So much for thinking that my car (March 2020) had escaped unscathed from the various foibles that seem to beset the Model 3
Are SCs likely to put much effort in to rectify it? i.e. surface prep etc, or is this going to be a thing I’m repeatedly going to have to go in for?

Just posting an update for people that look to install one of these spoilers themselves. Mine is still perfect and I am in the northeast with some pretty harsh climate.

I fitted the carbon after market one to my LR & its solid as a rock, but I cleaned the boot carefully with meths first. It's fixed with what looks like 3M tape!

Did it come with the top speed increase? When performance upgrade pack was an option (and even those that had it many early cars not even coming with the spoiler fitted for some reason), it was the car being configured with spoiler that governed the top speed increase.
