OEM Carbon Fiber wing install....question

[RS3USC]

So I have the OEM ond stupidly over-priced Carbon Fiber rear wing. My attempt(s) at install have been only with 3M. It does not fit correctly, there is a gap and does not seat correctly on the left side.

I contacted Audi and the answer is besides read the 100 page installation manual is to use industrial adhesive.

Not sure I want to for a host of reasons. Annoying that the knock off spoiler fits perfectly but the 1200 dollar one does not.

Have all of you used the super powere glue?

TIA

Audi has an oem adhesive you can buy specifically for it. I wouldn't use just a general adhesive when installing (yes i have the OEM CF spoiler and it didn't come with the oem adhesive)

So you were ok gluing it down then? Did you do it yourself?

When installing Audi suggests using this adhesive kit: 000071781A

Generally with all trunk lid spoilers of this shape/type there isn't always 100% perfect shape and a fairly strong adhesive is needed. Regular double sided tape won't do the job for a long lasting/worry free fitment, but automotive grade will along with prepping the trunk surface really well to ensure there isn't any oils, dirt, wax, etc on the area you are placing the spoiler on. If the gap is quite large then nothing will work.

Cheers,

Thank you for that. When pushing it in with force there is no gap, there is a lot of effort to hold in place to remove the gap. I was told that they start in the center and keep taping it down until reaching the end. I guess that would work but it sure seems like a lot of strain on the piece itself. The fitment is crap to be honest you with you. Very disappointing for something this expensive and OEM.

I paid my dealer $100 to have the Audi CF spoiler installed prior to pick up. They took it to a body shop and gave them the spoiler and the Audi adhesive. Worth the money in my opinion. I hate doing exterior things, as I have a tendency to screw them up.

[crazyprac]

This is an old thread but I just want to point out that the kit itself does not have the adhesive as I just found out. It has the tools to apply the adhesive. The adhesive itself is a different part number.

And like another poster in this thread, the fitment isn't better than your typical replica.

[Harordr]

Can you post a pic of the spoiler, im interested in seeing it

[crazyprac]

PM me your # and I'll send it over.

I worry about putting any super strong adhesive (even OEM) after the fact on your beautiful blue paint. It will look great of course once its on.

Anyone have the adhesive part number? Wanting to use it for carbon side skirts.

For those that have the OEM spoiler, did you have an auto body shop or the dealer install or did you do it yourself?

I have the spoiler and adhesive on order and am deciding on who would be best to install.

A local dealer wants 2 hours labor to do it, but I’m wondering if a body shop would do a better job at install or a dealer?

[Harordr]

I dont think it's challenging enough to pay someone to put on. I recently put on my spoiler and just take your time and you will be fine. After removing the stock one, polish the truck lid then use a good cleaner to clean it. Before putting the adhesive on, put the spoiler on the truck and put pieces of tape at the edges so you know where to place it when the adhesive is on it.

Any chance you would be willing to take pics of a test fitment and post them here? I'm curious about the fitment. I still find it hard to believe an OEM piece did not fit well given how well the OEM mirror caps fit, then again, I assume the spoiler is full CF, whereas the mirror caps are plastic with CF covering.

Does it seem to fit well? Do you think adhesive is needed? Say the spoiler got damaged and adhesive was used to install it - this means a complete trunk repaint would be needed in order to remove it? Oof

Still waiting on the spoiler to arrive, but as soon as I get it, I will try.

It’s all carbon and I believe it a good fit from what I’ve read. The issue is you need a strong adhesive to make sure it’s down completely, which is why the OEM adhesive is recommended. I’m guessing it’s the same adhesive that’s used for the stock spoiler, so I don’t think it’s an issue if it needs to be removed. The surface should just need to be completely cleaned.

A local body shop here quoted me $200.

I used the outdoors version of the double sided gorilla tape. The kind that looks like 3M. It’s that foam stuff. Covered as much of the spoiler surface as I could. It has stayed on as solid as day 1 for 2 years now in the rain, snow, summer heat and at off-road speeds. The OEM black spoiler is also held on with similar tape.

[Jonnylaw]

Does anyone have the instructions/manual for the CF rear spoiler?

I just received my OEM CF spoiler and it came factory sealed and the part is correct, but the manual included was for a front spoiler and not a rear spoiler.

[jd_rs3]

I'm sorry I don't have instructions, but I'll look up the service manuals shortly. Would you mind posting some detailed and close up pics of the spoiler, top and bottom? I'd love to see what it looks like in hand!

The back of mine has a slightly different sticker. Looks to be great quality. I would expect it to be since it’s OEM.

The spoiler I received came with no tools, just the spoiler and a manual (for a front spoiler not a rear one 😡). Did your spoiler come with tools to apply the adhesive, or dies the adhesive kit come with the tool?

The adhesive you posted is for a Q7? The adhesive kit recommended for the RS3 CF spoiler is this one:

[agpatel]

Is that kit just the tools for cleaning and priming or does it actually have adhesive in it? Both should work fine as the 009100A2 is urathane glue which will essentially do the same as something like Betalink 1K.

I did it myself.. the fitment was spot on and IMO is the best fitting / looking spoiler out there. I used 3m tape and an adhesive promoter to install.

[henhead]

Anyone been able to find a good deal on these yet? The mirror caps dropped significantly, hoping these will do the same at some point.

This is what was used when mine was put on back in 2017. I doubt the adhesive cares if it’s on an RS3 or a Q7:)

You’re correct. It’s just tools for prepping and application. The manual recommends:

Adhesive d172200a1 (80ml) or d172200a2 (310ml) both appear discontinued.

And plastic cleaner d195850a1 (also discontinued in us it seems).

You can buy the OEM version for $786 from one of the online Audi parts supply sites.

I don’t know how anyone is installing the OEM carbon fiber spoiler with just 3m tape. The only real flat surfaces are on the side and are small. Body shop I go to won’t use glue if they don’t have to and they said in this case they have to in order for it to secure properly.

I imagine the underside of the OEM wing is different from my Chinese version, but I'll say it feels like the strips of 3m tape on mine have good contact on the sides and top (closest to the rear window) with the trunk lid. The 2nd strip of tape towards the back edge of the trunk lid has decent, but not great contact, although some time in the sun for it to warm up has helped. Overall, it feels very firm and I think would take a good amount of force to remove. Glue is probably a better option but I am hopeful the tape will hold up, although I'm not sure what will happen in the winter. I have read that the OEM more or less requires the glue to adhere properly...

It does look really nice! Looking forward to pics once yellow tape is removed.

^^thank you. Will post more pictures when I remove the tape tomorrow. I was told there is a very slight gap on each side where the spoiler goes over the lip. Trying to shave it down in those areas or forcing it down by bending I was told could lead to micro cracking of the weave over time. Body shop (who I trust) said fitment is on par with OEM Audi or BMW. Looks good overall and the shop said it’s closest as it’s going to get. I’ll get a better look when I pick the car up today. These pictures were sent by the shop. Either way it’s permanently on there now that’s its glued on lol.

[Jonnylaw]

So while I’m waiting for everything to cure with the tape still on, I can definitely see a small gap between the spoiler and the trunk where it rolls over on each end. Hardly noticeable on the left side but more visible on the right. No other gaps or seams on top or bottom. All other areas are completely flush with the trunk. It’s not going anywhere lol.

I’m not sure how someone can get absolute perfect fitment install on this type of pure dry carbon over the lip spoiler, even OEM. Unless my OEM spoiler is just slightly off.

I’ll post pictures when I take the tape off tomorrow.

[jd_rs3]

My theory is related to the spoiler curving all the way around the trunk lid edge. It's hard to get that curve perfect with a mostly hand made piece like this. The reason the Chinese spoiler fits well is because it does not make that curve as much as the OEM and others do. Can you confirm?

Mine cuts off at the red line and OEM goes below that

I believe you are correct. I will post more pictures but yes, OEM wraps over that edge and this is where the fitment issue seems to be. The manual refers to this area as a “joint”, which extends pass where the repros do.

It’s glue on there now, so nothing can be adjusted afaik. When I take off the tape, I’ll get better pictures.

Ok, so I took the tape off. The carbon fiber itself is of high quality and looks great. There’s still some residual adhesive that needs to be cleaned off before protective film and ceramic coat is put on.
Top and bottom, everything appears flush and completely laid flat against the trunk. There is no flex. But, on the very ends, there is a small gap on the side and bottom. The right side is a little more obvious. This is fairly disappointing because for $1000 OEM adhesive, I guess I was expecting near perfect fitment (I get hand made dry carbon is difficult to fit). Granted I got the OEM spoiler from an Audi dealer online ons sale for $750 shipped.

This was also the reason I opted for the Audi suggested adhesive because of possible fitment issues with just using 3m ds tape. The shop was actually going to go with tape, but recommended against it because there wasn’t enough flat surface area to secure properly in their opinion.

I trust this shop so I think it’s a fitment issue with Audi, unless the install wasn’t done correctly. Both sides are line up properly. It’s just the small gaps under the lateral joints.

The shop said they can fill in the gaps with black silicone to make it look better? Should I have them do that or leave it alone? My OCD thinks I should have them fill the gaps with a little black silicone as suggested so the gap isn’t visible. Or is that not a good idea?

As far as removing it now or later, the shop said they can do it, but there’s a 1/3 chance the paint gets damaged when doing is, so I’m not jumping to do that right now because of the risk. In retrospect, maybe I should of have tried the DS tape, but I think the fitment would be even worse without the silicon.

Anyways, here are pics, please let me know what you all think:

Thx!

[jd_rs3]

Thanks for sharing all of the pics and sorry you are going through this. This thread has been very informative (and frankly, eye opening). I think the carbon fiber itself looks amazing and the overall quality of the part is fantastic. It is disappointing to have fitment issues on a $1000 OEM part, so I empathize with you there. I too would expect perfect, or near perfect fitment and have up until now remained skeptical of other reviews that mentioned fitment issues with the OEM spoiler. I agree the fitment issues are due to the design of the part itself (not the body shop's fault), specifically the lateral joint (as mentioned earlier). I'm hesitant to recommend black silicone, as that could add insult to injury, but it might help settle your OCD.

At the end of the day, you are most likely the only person that would ever notice these fitment issues, so the decision to add silicone or remove the spoiler all together is based solely on your ability, or lack there of, to live with it the way it is. From an outsider looking in, it's an awesome looking part that really compliments the car's rear and most people would never notice (or even care) that the fitment wasn't perfect.

If it were me, I'd leave it the way it is and move on.

[Jonnylaw]

So after reading through some posts on BMW forums with similar spoilers where betalink is used, it seems clamps on the lateral joints are used to get closer to adhere. Fairly sure it’s too late to do something like that now, but I’m going to take it back to the shop to see. Thank you Jd_rs3 for the reply.
