BMW M3 (G80) / M4 (G82) CS Style Carbon Fibre Rear Spoiler

The Carbonwurks M3 (G80) & M4 (G82) Coupe CS Style Carbon Rear Boot Lip Spoiler. Genuine Autoclave Pre-Preg Carbon Fibre. Lightweight Aggressive OEM+ CS Design.

Enhance the rear profile of your BMW M3 or BMW M4 with this CS-style carbon fibre rear spoiler, inspired by the design language of the exclusive G8X CS models.

Within BMW’s performance hierarchy, the CS (Competition Sport) designation represents a more focused, lightweight and track-influenced evolution of the standard M car. These models incorporate refined aerodynamics and more assertive styling to reflect their increased performance intent. This spoiler captures that ethos, featuring a more pronounced profile than the standard factory carbon lip to deliver a sharper, more purposeful rear aesthetic.

Manufactured from high-quality pre-preg carbon fibre, it provides a premium motorsport-grade finish while maintaining an OEM-plus appearance that integrates seamlessly with the factory body lines. The enhanced design improves visual balance at the rear and adds a performance-driven character without appearing aftermarket.

Please note, the photos currently being showed are for the M4 Coupe, we offer the same style for both the M3 & M4 Coupe that are specific to each car. Please select the correct boot spoiler for your car in the drop down menu.

Specifications

• Autoclave, Pre-Preg carbon fibre
• 3K 2×2 Twill – OEM weave
• High gloss UV resistant lacquer/clearcoat
• Pre-installed high bond acrylic double sided fitting tape
• Coated with RaceGlaze 55 high carnauba wax

For those who don’t know much about Pre-Preg Autoclave carbon, this is the strongest and lightest carbon fibre available. The rear spoiler 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 bootlid rear spoiler 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.
