BMW M3 (G80) M4 (G82) Coupe M-Performance Flow-Through Carbon Fibre Rear Spoiler

The M3 (G80) & M4 (G82) Coupe M-Performance Carbon Fibre Flow-Through Rear Wing Spoiler is Based on an OEM Design. Genuine Pre-Preg Carbon Fibre

From factory, BMW pre-install a small lip spoiler for the M3 & M4. If you spec the “Carbon Pack” this will be in carbon fibre unless you decide to go for the extremely expensive “M-Performance” pack as an aftermarket option which then includes the larger flow-through rear wing.

We have based our own “M-Performance” flow-through big wing on the OEM original but at a more cost effective price without compromising quality or fitment. Our design provides an aggressive look for the rear of your vehicle and enhances the styling dramatically as well as helping increase rear downforce on the car. The added downforce dramatically helps increase rear end stability under fast cornering and high speed braking. This is made with the same 2×2 twill carbon weave BMW use for their parts.

The Carbonwurks carbon fibre rear wing includes the M-Performance UV resistant vinyl lettering already applied to give you that true OEM look. This can be removed if preferred.

Please note, the fitting kit included is a Genuine BMW fitting kit and is specific to the M3 and the M4. Upon ordering please choose which version car you have in the drop down menu. Although this boot spoiler could potentially be installed without the fitting brackets/fixing kit, we strongly recommend against doing so. This rear wing produces a significant amount of downforce and as such it needs to be properly reinforced with adequate load-spreading bracket to prevent the spoiler damaging the tailgate or worst still, being completely pulled off the boot. The potential risks of installing this in the incorrect way are too high not to use the correctly designs brackets and fixings.

  • Autoclave, Pre-Preg carbon fibre
  • 3K 2×2 Twill – OEM weave
  • High gloss UV resistant lacquer/clearcoat
  • UV resistant M-Performance vinyl lettering
  • Coated with RaceGlaze 55 high carnauba wax
  • Genuine BMW fitting kit (fixings and brackets)

For those who don’t know much about Pre-Preg Autoclave carbon, this is the strongest and lightest carbon fibre available. The rear wing is cooked under immense pressure to give a very uniform and pin-hole free finish. With this being cured at high temps, it ensures longevity of the spoiler. The rear spoiler is then finished in a UV, high gloss lacquer before being hand and machined polished and being treated to a high content carnauba wax from our partners Race Glaze.


Fitment will require additional fixing points to be installed in the tailgate and for it to be drilled with 4 holes. With the fitting kit, included is a drilling template and all required fixings and brackets for installing this spoiler in the correct way. We always recommend using a competent bodyshop to undertake the installation. We standby our quality and fitment of all our parts. With all our products we produce and sell, every component is designed to stand the test of time along with giving as close to OEM fitment that can be achieved.
