Description
Disclaimer: A part that has been painted is no longer returnable regardless of warranty.
Refine the rear and side profile of your Porsche 911 997.2 with the Better Bodies Motorsport Rear Diffuser & Side Rockers Kit. This two-piece polyurethane aero package is designed for owners who want to enhance the car's rear three-quarter appearance and create a lower, more planted stance without modifying the front end.
The rear bumper diffuser adds definition beneath the factory rear bumper with a clean, motorsport-inspired profile, while the side rocker panels extend and sharpen the lower body line along the vehicle's sides. Together, the components create a cohesive appearance that gives the 997.2 a more aggressive and purposeful stance from multiple angles.
Both components are molded from Better Bodies Motorsport's proprietary polyurethane blend, providing flexibility, durability, and impact resistance for real-world driving. Unlike rigid fiberglass or brittle ABS plastic, polyurethane can flex under minor impacts and return toward its original shape, helping resist cracking and breakage.
The kit arrives in a raw black finish, ready for standard body-shop preparation, including scuffing, priming, and painting in your factory-matched or custom color.

Installation
The Better Bodies Motorsport Porsche 997.2 Rear Diffuser & Side Rockers Kit is designed for direct bolt-on installation using existing OEM-style mounting points.
The rear diffuser integrates with the factory rear bumper mounting locations, while the side rockers use factory-style mounting points along the vehicle's rocker panels.
Experienced DIY installers or independent Porsche shops can complete the installation, but professional installation is recommended for proper alignment, secure mounting, and the cleanest finished appearance.
If the components are being color-matched, standard body-shop preparation is required, including scuffing, priming, and painting.
Material & Construction
Both components are molded from Better Bodies Motorsport's proprietary polyurethane blend, combining flexibility, durability, and impact resistance.
Unlike rigid fiberglass or brittle ABS plastic, polyurethane is designed to flex under minor impacts and return toward its original shape. This makes the material particularly suitable for lower-body aerodynamic components that can encounter curbs, steep driveways, and road debris during everyday driving.
The kit arrives in a raw black finish, ready for body-shop preparation and painting.
Appearance
The rear diffuser gives the factory rear bumper a more defined and performance-oriented appearance, while the side rockers extend the lower body line to create a sleeker and more planted profile.
Together, these components tighten up the 997.2's rear three-quarter appearance and provide a cohesive lower-body upgrade without changing the front-end styling.
Aerodynamic Benefits
The rear diffuser is designed to help manage airflow as it exits from underneath the vehicle, while the side rockers help define and streamline airflow along the lower sides of the Porsche.
The combination provides subtle aerodynamic refinement while primarily delivering a more aggressive and purposeful exterior appearance.
Fitment Disclaimer
Please verify your Porsche 997.2 configuration before ordering. Confirm Coupe vs. Cabriolet, narrow-body vs. wide-body, and Carrera vs. Turbo trim. Differences in rear bumper and rocker configurations may affect compatibility.
