Shipping calculated at checkout.
An OEM-style dry carbon rear diffuser that adds aggressive detail and aero function under the rear bumper of your G80 M3 or G82 M4.
Why owners choose it
- Genuine dry carbon — lightweight construction that trims rear mass
- Chassis-specific fit — hand-finished for seamless fitment to the factory bumper; direct bolt-on
- Functional fins — sculpted fin geometry aids high-speed stability
- UV-stabilized resin — holds the deep finish through seasons of sun
- Factory-look proportions — complements OEM body lines
Direct bolt-on, no modification. Professional installation recommended.

Confirm your chassis code & model year before purchase. Contact us with any fitment questions.
Genuine dry (autoclaved prepreg) carbon fiber in a deep 2x2 twill weave, finished with a UV-stable clear coat that resists yellowing. Lighter and stiffer than wet-layup carbon, with a glass-smooth surface and a consistent weave.
