Description
Disclaimer: A part that has been painted is no longer returnable regardless of warranty.
Transform the exterior of your Porsche 911 997.1 with the Better Bodies Motorsport Front Lip, Side Rockers & Rear Diffuser Aero Kit. This complete three-piece aero package is designed to create a cohesive front-to-rear performance appearance while maintaining the timeless proportions and factory character of the 997.1.
The package combines a GT3TEK polyurethane front lip, matching side rocker panels, and rear diffuser. The front lip gives the nose a lower, sharper appearance, the side rockers extend and define the lower body profile, and the rear diffuser completes the build with an aggressive, motorsport-inspired rear-end appearance.
All components are molded to complement the factory body lines of the 2005–2008 Porsche 997.1 and feature pre-marked mounting points for precise positioning. The front lip and side rockers include pre-installed 3M automotive-grade double-sided tape where applicable, along with mounting hardware, while the rear diffuser is designed to integrate with the factory rear bumper mounting locations.
Manufactured from Better Bodies Motorsport's proprietary GT3TEK polyurethane blend, the components offer a combination of flexibility, durability, and impact resistance. Unlike rigid fiberglass or brittle ABS plastic, polyurethane can flex under stress and return toward its original shape, helping resist cracking and breakage during normal driving conditions.
The kit is supplied ready for standard body-shop preparation, including scuffing, priming, and painting, if you want the components color-matched to your Porsche.

Installation
The Better Bodies Motorsport Porsche 997.1 Lip, Rockers & Diffuser Kit is engineered for OEM-style fitment, with each component molded to follow the factory body lines of the 2005–2008 997.1.
Each component features pre-marked mounting points for accurate positioning. The front lip and side rockers include pre-installed 3M automotive-grade double-sided tape where applicable, along with the necessary mounting hardware. The rear diffuser is designed to integrate directly with the factory rear bumper mounting locations.
Experienced DIY installers can complete the installation, but professional installation is recommended to achieve the best alignment, panel gaps, secure mounting, and finished appearance.
If the components are being painted, standard body-shop preparation is required: scuff, prime, and paint.
Appearance
This three-piece aero package creates a complete and cohesive exterior transformation for the Porsche 997.1.
The front lip lowers and sharpens the nose for a more aggressive stance. The side rockers visually extend the lower body profile, creating a sleeker and more planted appearance. The rear diffuser completes the look with a purposeful, motorsport-inspired rear-end design.
Together, the components provide a balanced performance aesthetic that increases the 997.1's road presence while preserving its recognizable Porsche styling.
Aerodynamic Performance
Although primarily designed as an exterior styling upgrade, the kit also provides aerodynamic benefits.
The front lip helps manage airflow beneath the vehicle and reduce front-end lift, while the side rockers help streamline airflow along the vehicle's flanks. The rear diffuser is designed to improve airflow separation as air exits beneath the vehicle, helping contribute to improved stability at speed.
Together, the three components are intended to provide a more balanced and confident feel during spirited driving without the unnecessary bulk of an extreme race-style aero package.
GT3TEK Polyurethane Construction
All components are manufactured from Better Bodies Motorsport's proprietary GT3TEK polyurethane blend, combining flexibility with durability and impact resistance.
Unlike rigid fiberglass or brittle ABS plastic, polyurethane can flex under stress and return toward its original shape. This makes the material particularly well suited to everyday driving conditions involving curbs, steep driveways, road debris, and minor contact.
The flexibility also allows for fine adjustments during installation when necessary to achieve a precise, OEM-quality fit.
Impact Resistance
Polyurethane is designed for real-world driving conditions and can flex upon contact with road debris, curbs, and steep driveways rather than immediately cracking or shattering like rigid fiberglass.
Minor contact can still leave cosmetic scuffs or scratches, which can be refinished during standard body-shop preparation. Front lip scrape guards are recommended for additional protection in high-contact areas.
