OEM+ Carbon Fiber Trunk BMW G80 G20

BMW G80 M3 & G20 carbon trunk — the OEM+ signature everyone recognizes

This OEM+ style BMW G80 carbon trunk, made from genuine carbon fiber, is specifically designed for the BMW M3 G80 and 3 Series G20 (2018+). The OEM+ style retains the understated design of the original BMW M Performance trunk while enhancing the material with genuine carbon and a slightly pronounced BMW G20 carbon lip spoiler. It's the piece for owners who want to be recognized by enthusiasts without overdoing it: from a three-quarter rear view, your sedan changes status.

A design that transforms your BMW M3 G80

Faithfully reproduces the OEM design, with an integrated M Performance lip spoiler and a glossy 3K twill carbon fiber finish that reveals the full-thickness weave. The ideal compromise between subtlety and an assertive M Performance signature: nothing sticks out, everything is visible. In the sun, the weave animated by the clear coat gives a depth that neither a wrap nor a carbon-effect paint can imitate.

The extended compatibility with the standard 3 Series G20 allows you to transform a classic sedan into a visual replica of an M3: a 320d or 330i fitted with this BMW 3 Series G20 carbon trunk instantly gains the rear stance of the M model. Along with the wheels, it is one of the few modifications that can be seen from twenty meters away.

Material & quality of an exceptional carbon piece

Pre-impregnated carbon fiber cured in an autoclave, with an integrated rigidity frame to ensure structural integrity and proper operation of the struts. High-resistance two-layer anti-UV polyurethane clear coat. Weight reduction of around 4 kg compared to the original steel trunk, taken from the very rear and high up, where every kilo counts. Proven resistance to intense UV rays, road salt, gravel projections, thermal variations, and repeated high-pressure washing.

• Pre-impregnated carbon fiber cured in an autoclave — a high-end process, far removed from hand-molded wet carbon
• Integrated BMW G20 trunk spoiler — M Performance lip designed into the piece, no visible seams
• Weight reduction of around 4 kg — mass removed from the rear and high up compared to the steel trunk
• Glossy clear-coated carbon finish — visible 3K twill weave, depth impossible to imitate in paint
• M3 G80 look on 3 Series G20 — immediate visual conversion of a standard sedan
• Integrated rigidity frame — long-lasting fit and normal opening operation

Installation on your BMW G80 or G20

Compatible with BMW M3 G80 (2021+) and BMW 3 Series G20 (2018+). This is a complete replacement of the original trunk, with the transfer of electrical mechanisms: rearview camera, lock, sensors, and hands-free opening if your vehicle is equipped with it. Installation is carried out in a specialized bodywork garage, for the alignment of the gaps with the fenders and taillight, and for the re-balancing of the struts adapted to the new weight. Allow 2 to 3 hours. The installation of a carbon trunk is not an improvised garage job: it is the price of a factory-quality result.

Carbon trunk or simple trunk spoiler: which should you choose for a G20?

A BMW G20 trunk spoiler sticks to the existing sheet metal and costs a fraction of the price: it is an excellent first step. The full carbon trunk plays in another category. It replaces the bodywork element, eliminates all seams and any risk of peeling, lightens the vehicle, and displays carbon across the entire visible surface — not just on a lip. If your project aims for a polished BMW M3 G80 build, this is the piece that sets the tone for the entire rear.
