ETi Nissan 350Z Seido Rear Diffuser

Product Description

Complete the aggressive rear profile of your 350Z with the ETi Seido Rear Diffuser—a bold aero upgrade designed to enhance airflow, increase visual depth, and perfectly complement the Seido rear bumper and widebody setup. With sharp fins and a sculpted performance-focused design, this diffuser gives your Z a true track-inspired presence.

Ideal for widebody builds, stance setups, and high-performance street cars looking to elevate their rear-end styling.

✨ Key Features
• Seido Performance Design – Features aggressive fins and deep contours that add aerodynamic function and visual attitude.
• Elite Ti Craftsmanship – Built with precise molds, clean edges, and accurate fitment to the 350Z platform.
• Material Options – Available in FRP or Carbon Fiber, with dry carbon and custom weave options available on request.
• OEM+ Fitment – Designed to pair seamlessly with the Seido Rear Bumper for a clean, bolt-on installation.

🔧 Why Upgrade?
The stock 350Z rear lacks the aero definition and strong character needed for serious builds. The Seido Rear Diffuser adds depth, improves rear airflow, and completes the aggressive silhouette—whether you’re building for street, show, or performance.
