Porsche 997.1 Rear Diffuser – RUF/Strosek-Style, Carrera & 4S (2005–2008) — A tuner-inspired rear diffuser that gives your 997.1 an aggressive, race-bred rear end while smoothing underbody airflow for added stability.
Fitment
Fits Porsche 911 997.1 Carrera and Carrera 4S (2005–2008). Confirm rear bumper and exhaust configuration before ordering.
Material & Construction
Molded from Better Bodies Motorsport's flexible, crack-resistant polyurethane — it flexes over curbs, driveways, and road debris and returns to shape instead of cracking like fiberglass or ABS. Arrives in raw black, ready for scuff, prime, and paint in your factory or custom color.
Installation
Direct bolt-on using OEM-style mounting points and included hardware — no cutting or welding. DIY-capable; professional installation recommended for the cleanest alignment and finish.
