BMW M5 F90 LCI | Prepreg Dry Carbon Fiber Front Grille

BMW M5 F90 LCI Prepreg Dry Carbon Fiber Front Grille

Engineered for BMW M5 F90 LCI (2021-2023 facelift) owners who demand premium quality, this Prepreg Dry Carbon Fiber Front Grille is the carbon-fiber evolution of the M-style kidney grille. Imported from leading manufacturers around the world and quality-controlled by BYC Performance, this BMW M5 F90 LCI carbon front grille bolts directly to OEM mounting points and preserves full OEM compatibility with the front camera, parking sensors, and adaptive cruise control radar.

If you're building a serious BMW M5 F90 LCI tuning project and want a part that exceeds the factory plastic grille in finish and weight, this dry carbon front grille is built for you. Autoclave-cured prepreg carbon fiber is noticeably lighter than wet-lay parts, with strong structural integrity and outstanding long-term UV resistance. Engineered to match the bold character of the S63-powered F90 LCI M5, 617 hp Competition and 635 hp M5 CS.

Key Features

• Prepreg (Dry) Carbon Technology: Pre-impregnated carbon plies cured in an autoclave under high heat and pressure ensure more consistent resin distribution and a more consistent weave.
• M-Style Kidney Grille: F90 LCI-specific design; single-piece carbon construction for a premium appearance.
• Camera & Radar Compatible: Cutouts and mounting points for OEM front camera, parking sensors, and adaptive cruise control radar are retained.
• Weight Savings: A worthwhile weight saving over the factory plastic grille.
• 2x2 Twill Carbon Weave: Authentic carbon fiber pattern under a high-gloss UV-protective clear coat.
• Direct OEM Fit: Plug & play installation on factory F90 M5 LCI mounting points.
• UV & Chemical Protection: Long-life clear coat protects against fading, cracking, insect splatter, 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

Installation Notes

Installing the BMW M5 F90 LCI carbon front grille is a direct replacement of the factory part. Professional installation is recommended:

2. Detach the OEM grille after disconnecting the camera and sensor connectors.
3. Test-fit the carbon grille for alignment.
4. Reconnect camera and radar connectors to their original housings.
5. Secure with supplied hardware to the manufacturer's recommended torque.
6. Verify adaptive cruise control calibration after installation.
