BMW M4 F82 F83 Pre-Preg Carbon Fibre Rear Spoiler V2 Final Edition by Adro (2014-2020)

The F82 deserves a proper farewell. The Final Edition Spoiler is the second iteration of ADRO's M4 spoiler - refined from everything ADRO learned building the original and built to be the definitive version for this chassis. Available from Forge Automotive supply only, or fitted at our sites in Darwen and Leeds.

The spoiler sits flush along the trailing edge of the trunk lid: subtle, deliberate, and exactly where it should be. Paired with the full Final Edition kit, the complete aero package delivers +257N (58 lbs) of downforce with just +63N (14 lbs) of added drag over stock.

No modification to the trunk lid required. Installs with 3M double-sided tape.

Prepreg carbon fiber starts with resin pre-impregnated into the fiber at the factory, then cured under heat and pressure - producing a precise, consistent resin-to-fiber ratio that wet lay simply can't match. It's the same process used in motorsport and aerospace. The difference shows in the finish, the weight, and the structural integrity of the part.

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.

Fitting is available on every part at our North West (Darwen) and Yorkshire (Leeds) workshops. Prefer to fit it yourself? Fitting instructions ship with every part.
