2021-2025 BMW M3 G80 M4 G82/G83 BKSS Style Carbon Fiber Front Lip

Enhance the front profile of your BMW M3 or M4 with this BKSS style carbon fiber front lip. Designed to create a lower and more aggressive appearance, this exterior upgrade adds a bold track-inspired accent while complementing the vehicle’s factory body lines.

The sculpted BKSS style design enhances the vehicle’s aerodynamic presence by helping manage airflow around the lower front bumper. Its performance-focused contours give the front end a sharper and more planted stance suitable for street, show, and track-inspired builds.

Crafted from CFRP, FGCF, or DryCF material options, this front lip combines lightweight construction, durable exterior performance, and premium finish quality. Designed for 2021-2025 BMW M3 G80 Sedan and BMW M4 G82 Coupe and G83 Convertible models, each package includes one front lip.
