BMW M2 G87 & 2 Series G42 Pre-Preg Carbon Fibre Duckbill Rear Spoiler by Adro (2023 on)

The ADRO Carbon Fibre Duckbill Spoiler is the ultimate blend of form and function for the BMW G87 M2 and G42 2 Series. Designed to improve both aesthetics and aerodynamics, its unique pass-through design optimises airflow, reducing drag while maintaining downforce for improved stability. The duckbill geometry provides a more assertive rear profile than a conventional lip spoiler - adding visual drama whilst delivering genuine aerodynamic contribution. Forge Automotive supplies this spoiler and can fit it at our Darwen and Leeds sites.

Crafted from premium pre-preg carbon fibre, this spoiler gives exceptional strength-to-weight with a deep, uniform gloss finish. Installation uses 3M adhesive tape (included) for a clean, hardware-free fitment.

Supplied, fitted and finished by Forge Automotive

Forge Automotive can fit this spoiler at either of our sites: Darwen in the North West or Gildersome, Leeds in Yorkshire. Forge Automotive can also finish this spoiler before fitting: paint protection film (PPF) to guard the carbon, a colour change or satin wrap, or colour matching to the car. Ask when ordering.

Common questions

What is pre-preg carbon fibre?
Pre-preg is carbon cloth that arrives from the mill already impregnated with a measured amount of resin. The part is laid up in the mould and cured under heat and pressure, usually in an autoclave or oven. Because the resin content is controlled, the finished part is lighter, stiffer and more consistent than a hand-laid one, with a cleaner weave and better dimensional accuracy. It costs more to make, which is why pre-preg parts sit at the top of a range.

What does "dry carbon" mean?
Dry carbon is the everyday name for a pre-preg part: carbon fibre all the way through, rather than a carbon skin over a fibreglass or plastic base. The surface still has a clear lacquer, but there is no excess resin in the laminate, so the part is light and rigid.

What is a 2x2 twill weave?
The weave pattern in the carbon cloth. In a 2x2 twill each strand passes over two and under two, which gives the diagonal pattern BMW use on their own M Performance and M carbon parts. Choosing 2x2 means aftermarket and factory carbon on the same car match.

How do I look after a carbon fibre part?
Treat the lacquer like paint: wash with pH-neutral shampoo, avoid harsh solvents, and wax or seal it. UV is what ages carbon, so a protected finish lasts longer. Forge Automotive can apply paint protection film to any carbon part before fitting, which guards against stone chips and keeps the weave clear.

What makes the duckbill design different from a conventional rear spoiler?
The duckbill's pass-through geometry allows air to flow through a section of the spoiler, reducing drag whilst the spoiler element itself maintains downforce. This gives a more aerodynamically efficient result than a solid spoiler of the same height, alongside a more distinctive visual profile.

Is drilling required for installation?
No. Installation uses included 3M adhesive tape for a clean, hardware-free fitment.
