Product Overview

The Carbon Fiber Rear Bumper Splitter Fins for BMW G80 M3, G82 M4, and G83 M4 are designed to create a more defined and performance-focused lower rear profile. Their vertical fin geometry follows the factory bumper and diffuser lines, adding a sharper motorsport accent without replacing the complete rear diffuser assembly.

Manufactured from lightweight CFRP with a glossy 3×3 twill weave, these BMW carbon fiber rear bumper fins offer high rigidity, premium surface quality, and durable exterior protection. Precision tooling and vehicle fitment checks help ensure clean positioning, while adhesive and hardware-assisted installation supports efficient workshop fitting.

This product is suitable for BMW tuning brands, carbon fiber parts distributors, installation shops, and private-label aftermarket programs.
