BMW M3 G80 / M4 G82 | Prepreg Dry Carbon Fiber CSL Front Grille (ACC)

BMW M3 G80 / M4 G82 Prepreg Dry Carbon Fiber CSL Front Grille (ACC Compatible)

Engineered for BMW M3 G80 and M4 G82 owners who want to transform the factory twin-kidney grille into the M4 CSL look, this Prepreg Dry Carbon Fiber CSL Front Grille features an integrated Adaptive Cruise Control (ACC) radar cutout so your driver-assist sensors continue to operate at OEM performance. Autoclave-cured by leading manufacturers around the world and quality-controlled by BYC Performance, this BMW G80 / G82 carbon CSL grille uses factory clips and mounting points for plug & play fitment.

If you're building a serious BMW M3 G80 tuning or M4 G82 modification project and want a single-part dramatic front-end transformation, this dry carbon CSL grille is the answer. Open-grille design improves airflow to the S58 engine's main radiator and oil cooler, important on the 473 hp standard, 503 hp Competition and 543 hp CS/CSL trims. The same grille form fits the M3 G80 Sedan, M4 G82 Coupé, and M4 G83 Convertible.

Key Features

• Prepreg Dry Carbon Technology: Cured under high heat and pressure in an autoclave for a more consistent weave.
• CSL Design Language: Carbon version of the M4 CSL front grille; far more aggressive than the OEM plastic grille.
• ACC Radar Compatible: Integrated ACC radar cutout; driver-assist sensors work without modification.
• Improved Airflow: Open grille design pushes more air to the S58 main radiator and oil cooler.
• 2x2 Twill Carbon Weave: Authentic carbon pattern under a UV-protective high-gloss clear coat.
• Direct OEM Fit: Plug & play installation on factory G80 Sedan and G82/G83 Coupé/Convertible clips and mounting points.
• UV & Chemical Protection: Long-life clear coat protects against fading and fuel/tar splash.

Prepreg Dry Carbon vs. Wet Carbon: Which Is Better?

Most aftermarket carbon parts are made using wet lay-up, where resin is applied by hand and cured at room temperature, leaving air voids and inconsistent weight. Prepreg (dry) carbon:

• Cured in an autoclave under high heat and pressure → a more consistent weave
• A controlled resin ratio → lighter and stronger
• The production method widely chosen in motorsport
• Minimal UV fading over years of use
