BMW M4 F82 Pre-Preg Carbon Fibre Rear Boot Spoiler by Adro (2014-2020)

While some of the F82 BMW M4s have the optional rear trunk spoiler from the factory, a lot of owners find that it's not quite bold enough for their car; especially if they have a lot of other carbon fiber or cosmetic modifications installed. ADRO developed this hand-crafted carbon fiber spoiler for the BMW M4 that draws some inspiration from the optional OEM spoiler, but adds a whole new level of presence. This carbon fiber BMW M4 spoiler sits higher than the factory spoiler and has angled edges to compliment the sharp edged styling of the F82 M4. Plus, you may even feel a slight increase in downforce when compared to the OEM counterpart, thanks to its elevated and more aerodynamic design that allows for more air to pass under the wing to create more downforce. This carbon fiber spoiler is one of the easiest parts to install and will immediately take your M4 to the next level in performance and design. Forge Automotive supplies this spoiler and can fit it at our Darwen and Leeds sites.

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.
