Rear wing addition

Back ground: I bought used a 2015 without a wing. I actually like the car without a wing, just makes it more stealthy. Being a Mod'er, I started looking at wings. The factory wing while nice, I thought was ridiculously priced so I searched for options and came across this wing on eBay. I liked the lines and it was a China knock off, so it was cheap (under 300). I have had plenty experience with China knock parts. A good China knock off typically requires some tweak and a bad one requires, well a lot of tweaking to make it work. Being a Mod'er or DIY type guy I, I rolled the dice.

This piece was a horrible knock off (maybe a barbus wing knock off). When I fitted one side, there was a 1/4 inch gap on the other side! Being carbon fiber, it wasn't going to bend or give to address the gap. Threw on a shelf were it has sat for over a year. Had time so down it came off the shelf and work began. To address the gap, I cut the wing in half, and removed 3/8 of an inch in the middle of the wing. Fitted each piece to the car with 3m tape. Reconnected the 2 pieces with epoxy and wooden dowels on the car and let set. Then bondo, sanding, more sanding and off to paint. On the curved section, it was not matching the curved of the car, creating a few points that required 3 layers of 3m tape to fill! To address this aesthetically, I filled it with caulk (Easy enough since the car is white).

So here is the end result. Some will like it others will not.

Hard to explain but if the piece on the sides was larger, matching the oem hatch then black would be an intesresting option. The way it is, other than white makes it look less integrated.the pic below also illustrates the caulk used to fill the curvature gap. At times I really wondered if this was ever meant for a 45 amg.

The only other thing I have done is a radar detector mount under the rear view mirror otherwise she is stock. Fun DD! The 45 amg to me is MB version of a WRX STI or EVO. Grown up version.

Nice work on the wing! Thanks for sharing your story, and reminding us that sometimes you need to apply a little elbow grease to get what you want. You definitely had to do a lot of work to get that top look so good. Looks factory to me from the pics. Definitely worthy of "custom" status though.

To hesitate is a waste of time.

Just curious but is there a post-delivery wing removal that's not too intrusive and with good end results (similar more stealthy intent)? I presume holes to be grommeted, and/or just tape removal? Will the dealer remove it? Thanks.

Maybe a parts diagram would show some of those details? I've not seen one removed before.
