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.

Main Feature

✅ Designed for BMW E34 M-style bumpers with a clean, understated OEM+ look
✅ Provides aerodynamic improvements by smoothing rear airflow and increasing downforce
✅ Weighs only 3.5kg — crafted from 2mm 6061 aluminum for strength without excess mass
✅ Laser-cut for precise fitment that follows original bumper contours
✅ Durable black powder-coated finish resists weather, corrosion, and road grime
✅ Includes stainless steel hardware and extra fasteners for easy and secure installation
✅ Ships with Rendition decal pack and all necessary hardware for installation

Installation

Just tap a few holes on the rear bumper & use existing mounting points to install!
