Overview
The RENDITION E34 Rear Diffuser is designed to do more than just look good — it brings functional aerodynamic benefits and a lightweight, OEM+ appearance to your E34’s rear end. By extending the lower lines of the M-style bumper, it subtly reduces drag and improves airflow, while staying true to the factory silhouette.
Crafted from precision-cut 6061 aluminum and finished in a durable powder coat, it’s the perfect finishing touch for enthusiasts looking to combine form and function.
