The G80 M3 trunk lid is clean but flat: no trailing edge, nothing to sharpen the rear silhouette. This competition trunk spoiler adds that edge in real carbon fibre: 2×2 twill weave with high-gloss UV-stable clear coat, identical in construction to OEM M Performance CF parts. At speed it improves rear downforce marginally; visually, it transforms how the car reads from behind.
Engineered for the G80 M3 and G20 3 Series trunk lid geometry for model years 2020–2024. Mounts to the existing boot lid using the factory attachment points: no drilling into the lid. Arrives ready to install.

Wow, this Carbon Competition Trunk Spoiler is a game-changer! I installed it on my 2020 BMW M3 G80, and the difference is night and day. The fitment is perfect—like it was made specifically for my car. The carbon fiber looks amazing in person, with a deep, glossy finish that just screams quality. And let me tell you, I’ve noticed a real improvement in stability at higher speeds. It’s not just for looks; it actually enhances performance. I couldn’t be happier with this purchase.

I’m not a hardcore car modder, but I wanted something to make my 2021 BMW G80 M3 stand out a bit more. The Carbon Competition Trunk Spoiler did just that! I was worried about the installation, but it turned out to be really easy. It adds just the right amount of aggression to the car’s rear. Great product!

I’ll admit, I was hesitant to spend this much on a trunk spoiler, but after installing it on my 2021 BMW M3 G80, I’m convinced it was worth every penny. The carbon fiber is really high quality—you can tell just by looking at it. It adds a cool, aggressive look to the car without being over the top. If you’re on the fence about it, go for it you won’t regret it!
