BMW M3 G80 G81 M4 G82 G83 M Bumper +LCI Grille Grille C4P

Paint Code: C4P (Brooklyn Grey Metallic) | 2024–2026

For the 2025/2026 LCI (Life Cycle Impulse), BMW maintained the core geometry of the front bumper but focused on lighting and trim updates. The code C4P refers to Brooklyn Grey Metallic, one of the most popular colors for the G8x generation, often paired with high-gloss black or carbon fiber LCI grilles.  BMW M3 G80 G81 M4 G82 G83 M Bumper +LCI Grille Grille C4P

1. The LCI Front Bumper (C4P)

The front bumper skin remains fundamentally the same between pre-facelift and facelift models. If you are ordering a replacement bumper in Brooklyn Grey (C4P), the part is usually delivered primed and requires paint matching to ensure the metallic flake aligns with your fenders.

• Bumper Part Number (Primed): 51118069415

• Color Match Note: Brooklyn Grey is a “flat-look” metallic. It is highly sensitive to the clear coat thickness; a professional shop must use the C4P formula to avoid a “mismatched” blue or yellow tint.

2. LCI Grille Options (Standard & CS)

The LCI grille design for 2025+ models is often swapped for the CSL/CS Style, which features fewer horizontal slats and a more open, motorsport-inspired look.

3. Technical Intelligence: Installation & Sensors

Critical Installation Advice:

• Bumper Removal: To change the grille on the G80/G82, the entire front bumper must be removed. It is held by roughly 15 screws on the bottom, 6 on the top, and 2 hidden in each wheel arch.

• PDC & ACC Sensors: When moving the grille components, the Parking Distance Control (PDC) sensors and the Active Cruise Control (ACC) radar must be recalibrated if the car displays a “Sensor Blocked” error after reinstallation.

• The M-Badge: The small “M3” or “M4” badge on the grille is not included with a new grille. You must carefully heat the adhesive on your old badge to transfer it to the new LCI/CSL unit.
