Tuner style meets function with the RUF/Strosek-style rear diffuser. Built for the 2005–2008 997.1 Carrera and Carrera 4S, it gives the rear an aggressive, race-bred look while improving airflow.
What is this rear diffuser?
It’s a rear bumper diffuser influenced by RUF and Strosek tuner designs, integrating into the lower rear bumper for aggressive detailing and smoother underbody airflow.
Why polyurethane?
Molded from flexible, crack-resistant polyurethane, it absorbs minor impacts and returns to shape instead of cracking like fiberglass. It arrives ready for scuff, prime, and paint.
Fitment
Fits the Porsche 911 997.1 Carrera and Carrera 4S (2005–2008). Confirm your rear bumper and exhaust configuration before ordering.
Installation tips
The diffuser uses OEM-style mounting points and includes hardware. DIY installation is achievable; professional fitment ensures the cleanest fit and finish.
Styling and performance
The diffuser adds an aggressive, tuner-inspired rear-end look while contributing to underbody airflow management — a distinctive upgrade for Carrera and 4S owners.
FAQ
Does it fit the 4S? Yes — it’s designed for both the Carrera and Carrera 4S.
Will it crack? Polyurethane flexes and resists cracking under normal driving.
