TREVORA G42 M240i Carbon Fiber Rear Diffuser

The TREVORA ID-01 Carbon Fiber Rear Diffuser for the BMW G42 M240i is a performance-oriented OEM+ exterior component designed specifically for the 2021+ G42 platform. Produced from premium pre-preg carbon fiber, the ID-01 diffuser offers a more visually defined rear bumper profile and contributes to improved aerodynamic efficiency by managing airflow beneath the vehicle's rear section.

The ID-01 features an aggressive three-fin design that references the rear treatment seen on recent BMW M coupes, adding a motorsport-informed character to the rear of the M240i. The fins are cleanly integrated into the diffuser body, producing a cohesive and purposeful appearance that complements the factory bumper lines without visual disruption.

Constructed from high-quality pre-preg carbon fiber, the diffuser delivers a lightweight component with a high-gloss surface finish and long-term structural durability. The pre-preg layup process ensures consistent resin distribution and weave alignment, producing a finished surface that meets OEM-grade visual standards.

Installation is designed for simplicity, using the factory mounting points and OEM clips as primary attachment hardware. No cutting or modification to the factory bumper is required, allowing for a clean, reversible installation.
