Seibon RD20TYSUP-MB MB-Style Carbon Fiber Rear Diffuser

The Seibon RD20TYSUP-MB is a MB-style carbon fiber rear diffuser, hand-crafted using professional-grade 3K 2x2 twill weave carbon fiber. Engineered for aerodynamic performance, this rear diffuser is designed to channel airflow beneath the vehicle for a clean, unrestricted exit at the rear. The aggressive MB-style design features larger fins on the sides and center, along with integrated cutouts for factory rear parking sensors.

Built by Seibon Carbon — a specialist in high-performance carbon fiber body components since 2003 — every component is produced to an exceptional carbon-to-resin ratio that maximizes stiffness and structural strength while keeping weight to an absolute minimum. The consistent 2x2 twill weave pattern delivers a clean, uniform appearance across the entire surface.
