Who here has installed a Renntech rear wing on a C190 coupe?
I need some help please. This wing kit has no water tray for water that gets under the spoiler mounting plate. it comes with 4 screws that do not line up with anything on the car at all. No one who sells them has instructions. No one has a parts list. How did you install it? I am thinking you have to remove the motor actuator plate and stock spoiler, remove the spoiler and freeking drill 4 holes in the black stock spoiler mounting plate?

Please LMK if you have a clue about this. TIA.
Unfortunately, the component you have does not have a workable base. It may resemble a Renntech design, but it lacks the structural provisions required for proper attachment and appears consistent with the generic, non-functional replicas often sourced from Alibaba.
For clarity, the fixed rear wing on the AMG GT platform is composed of two distinct elements:
The OEM wing base
The wing element that mounts onto that base
When purchasing a Renntech fixed wing component, you get only the wing, they clearly specify that the OEM base is mandatory and not supplied by them. Their wing is engineered to bolt directly onto that factory base and cannot be installed without it. Your current base does not include the necessary mounting architecture.
The OEM base itself is secured to the trunk lid with approximately fifteen fasteners. This high number of attachment points is essential because the combined base and wing assembly must withstand significant aerodynamic loading at high speeds without risk of detachment.
You can either attempt to improvise a solution that allows your replica base to interface with the fifteen OEM mounting points, or you can source the correct OEM base. The factory base is not a carbon fiber base and is supplied by Mercedes-Benz as items 600, 620, 630, and 640 (see diagram and list below)
Before purchasing, you will need to confirm that the two brackets on your replica wing align with the attachment points on component 600.
The alternative is to acquire the full OEM carbon fiber wing assembly.
Below is a diagram and a complete parts list for the factory AMG GTR wing system, which may assist you as you proceed with the project.
(Other AMG GT members, if you experienced this wing, please chime in).
Roger that on it looking like it will rip right off in the wind. I mean, with hundreds of pounds of downforce on a real wing, one should be able to stand on it, right?
I appreciate your providing the diagram. and the photo. enclosed is my GTS with a stock, actuated rear flush spoiler, so the mounting holes look the same.
I will probably sell this into the ether/online and talk to some OE manufacturers and also, scrutinize their install instructions before buying.
By the way, I know what you mean about "generic", as in: it will fit on Honda Civic if you drill hard enough.... but this wing was made "for" am AGT GT. The lower CF spoiler mount in my pictures fits right into the cavity left by the stock spoiler.
but I am thinking now, it was likely made for a spec with no actuated flush body spoiler. because of this statement from a website called XXII.
Installation Type - Replacement Rear Wing Spoiler with Carbon Base plate. Installed in the original position of the rear spoiler. Active Spoiler Designs will need to be deactivated to prevent damage to the spoiler or car. Professional Installation Recommended.
Models with no Active wing will require additional brackets to be made in order to install this spoiler as the original mounting points will not correctly line up on GTS Models with the original wing spoiler.
Do you have the diagram for an AMG GT with no actuator on the spoiler? or a link to your source, please? I want to compare notes. If the cavities and bolt holes are the same, then, I am SOL.

First, now that you provided the link to the wing, it is clear that the piece looks impressive and closely resembles the OEM GTR design. The situation is understandably frustrating, and there is hope that a clean solution will emerge.
Second, IMHO I think that there is no functional difference in the rear-wing mounting architecture across the GT, GTS, and GTC platforms from model years 2016 through 2021. Regardless of whether the car has a fixed or motorized wing, any conversion to a fixed GTR-style wing requires removal of the motorized mechanism and tray to free the mounting area.
It is worth removing the center cover of your new wing by extracting the four bolts and checking whether a drilled pattern can be created to align with the GTS fixed-wing mounting points. This will give you a clear view of what can be adapted.
yup, they all probably come from the same source in China, just sold under different Ebay users. I called RennTech and honestly, they were the most friendly and helpful of any of these varmints. verified the real RennTech spoiler just mounted to the stock mounts on a car that came "WITH" a wing spoiler already. No option for one with a flush spoiler.
I have plenty of experience with cars, but none with spoiler wings, it also occurs to me that this wing, if it is supposed to provide hundreds of pounds of downforce, one should be able to dance on it.
I would not dance on this wing. Nope...
So, get this, after weeks of back and forth (not every day, but maybe 2x a week, and them claiming this was the correct mounting plate and I. should "mount it in the groove"), I requested the vendor take the spoiler back and I asked for a refund, and THEN their "engineer" suddenly says they have an alternative mount plate, and finds a photo (at my request) of this, has the 14 holes. WTF? Idjits had the solution all this time.
I will let them send it, just for laughs at this point, I bet they still don't provide any weather stripping, or a way to drain standing water. More curious to just make a "avoid this crap at all costs" video for YouTube.
