Optimal Co 2019-2024 Glossy Black Trunk Spoiler Wing Compatible with BMW 3 Series G20 2020 2021 2022 330 330i 330e M340i

Good quality at a fair price. The fit and finish are perfect. The included double sided tape seems to be genuine 3M high strength (not the super high strength). There is not quite enough of it included, so order your self a couple more feet of 1/2 wide for maximum coverage. Fit and finish are perfect. Very easy to line up. Matches the curves. About 1/8 of inch left on each side of the trunk lid, which is exactly what I would expect. I did not want something over the top. I wanted it to be more subtle, and that it would not change the aerodynamics much if at all. I wanted to just add little touch of sporty, and this is exactly that. The black paint is a very true black. Perfect match to the shadowline option. Nice gloss to it. The form is great, but the OEM is ever so slightly better. BMW does not make this in gloss black, so this is the next best thing. No installation instructions, but there are plenty of YT videos. Apply tape to spoiler. Heat it with heat gun. Heat the application area on the car with heat gun. Apply to car with pressure. That's it. I live in SWFL and its August. Its already hot as hell, so the maximum bond strength is achieved easily. If you live where it is cold, you may need to take extra measures to get that maximum bond strength. Time will tell, but this spoiler looks fantastic. While I do not feel like it will last the lifetime of the car, I do feel like I will get a solid 3-4 years out of it. Eventually, the doubles-sided tape breaks down, and spoiler will begin to separate. If the spoiler is in otherwise good condition, this can be fixed with a bit of goo gone and more double sided tape. It happens to the OEM one's too. I got a C300 in my driveway right now with a factory spoiler that is separating because the tape broke down after a few years. It is what it is.

Good fitment and a year later and many automatic car washes, it's still on tight.

After 3 months it is falling off!! What can I do. I want to rip it off my car as it looks ugly nos

Easy to install, nice subtle upgrade from factory “bump” spoiler. Looks sharp and great value to save a little from the OEM price.

I have a 2020 M340i, it fits very well no fitment issues at all. The quality is great and the gloss black looks very nice. I would only recommend using 3M double strength tape instead of the tape that is included.
