Transform the rear-end presence of your F90 M5 with our CTM Style Carbon Fiber Diffuser, featuring an aggressive shark fin aero design and an integrated LED 3rd brake light for both performance styling and enhanced visibility.

This diffuser is a direct replacement for the OEM rear diffuser—not an add-on cover—ensuring a clean, factory-quality fit. The included dual vertical LED brake lights provide a modern motorsport-inspired appearance while improving safety by increasing rear visibility during braking.

Constructed from real 3K twill-weave carbon fiber, this diffuser is ultra-lightweight yet durable, finished with a high-gloss UV-resistant clear coat to prevent fading, yellowing, or discoloration over time.
