BMW M3 G80 / M4 G82 Prepreg Dry Carbon Fiber ST Front Grille

Engineered for BMW M3 G80 and BMW M4 G82 owners, this Prepreg Dry Carbon Fiber ST Front Grille is a vertical-slat carbon reinterpretation of the traditional double-kidney grille, giving the front fascia a driving-focused motorsport identity. Autoclave-manufactured in Europe and quality-controlled by BYC Performance, this G80 / G82 ST carbon grille mounts directly to the OEM front bumper — no cutting required.

Replacing the controversial large kidneys of the new-generation S58-powered M family (M3 Sedan G80 473-543 hp, M4 Coupé G82 473-543 hp) with a more aggressive carbon-accented look, the ST grille fits both M3 G80 and M4 G82 front bumpers identically — factory grille apertures are shared across both chassis. Autoclave-cured prepreg carbon fiber is noticeably lighter than wet-lay carbon and significantly more UV-resistant.

Key Features

• Prepreg Dry Carbon Technology: Pre-impregnated carbon plies cured in an autoclave under high heat and pressure; a more consistent weave.
• ST (Vertical Slat) Styling: Inspired by classic BMW M3 E30/E46 motorsport grilles.
• Full Carbon Detailing: Carbon frame and slats replace OEM chrome/black plastic grille.
• 2x2 Twill Carbon Weave: Authentic carbon fiber pattern under a high-gloss UV-protective clear coat.
• Improved Airflow: Vertical slats offer more open airflow than the OEM horizontal grille.
• Direct OEM Fit: Plug & play on M3 G80 Sedan and M4 G82 Coupé factory grille apertures.
• UV & Chemical Protection: Long-life clear coat protects against fading, cracking, fuel splash, and road tar.

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
