BMW M3 G80 & 3 Series G20 Pre-Preg Carbon Fibre Rear Spoiler V2 by Adro (2020 on)

The ADRO V2 Dual-Element Spoiler gives the BMW G80 M3 and G20 M340i a more bold yet refined rear profile. The V2 design introduces a dual-element configuration that adds depth and visual separation at the rear - creating a stronger presence while maintaining clean, OEM-plus lines that flow naturally with the factory boot shape. Forge Automotive supplies this spoiler and can fit it at our Darwen and Leeds sites.

Crafted from lightweight pre-preg carbon fibre, the V2 spoiler gives a deeper gloss and tighter weave than wet-lay alternatives, with a profile that complements the G80/G20 rear end without overpowering it. The dual-element design references motorsport aerodynamic principles while remaining appropriate for a road-focused build.

Installation uses the existing boot lid architecture - no drilling required. The spoiler is confirmed for both the G80 M3 and G20 3 Series, covering saloon and relevant body styles.

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.

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 is the difference between the ADRO V1 and V2 rear spoiler for the G80 M3?
The V2 features a dual-element design with two separate horizontal planes, adding greater visual depth and aerodynamic separation at the rear. The V1 is a single-element design. The V2 gives a more assertive appearance and greater rear presence.

Is this compatible with both the G80 M3 and the standard G20 3 Series?
Yes. The spoiler is confirmed for both the G80 M3 and the G20 3 Series (including M340i and M Sport). Fitment uses the standard boot lid architecture shared across both models.

Does fitting this require drilling?
No. Installation uses 3M adhesive tape and the existing boot lid mounting points - no drilling required.
