Description
Disclaimer: A part that has been painted is no longer returnable regardless of warranty.
Upgrade both ends of your Porsche 911 997.1 with the Better Bodies Motorsport Front Lip & Rear Diffuser Kit, a two-piece aerodynamic package designed to enhance the appearance and aerodynamic character of the 997.1 without overwhelming its original Porsche styling.
The kit combines a GT3TEK polyurethane front lip with a matching GT3TEK polyurethane rear diffuser, creating a cohesive front-to-rear aero upgrade. The front lip gives the 997.1 a lower, sharper, more aggressive stance, while the rear diffuser adds a motorsport-inspired appearance and helps manage airflow exiting beneath the vehicle.
Both components are molded to complement the factory body lines of the 997.1 and feature pre-marked mounting points for accurate positioning. The front lip includes pre-installed 3M automotive-grade double-sided tape where applicable, along with the necessary mounting hardware. The rear diffuser is designed to integrate with the factory rear bumper mounting locations.
Constructed from Better Bodies Motorsport's proprietary GT3TEK polyurethane blend, the components provide 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, making it well suited to everyday driving conditions. Minor adjustments can also be made during installation to achieve proper fitment and alignment.
The components are supplied ready for standard body-shop preparation, including scuffing, priming, and painting, if you want them color-matched to your Porsche.

Installation
The Better Bodies Motorsport Porsche 997.1 Lip & Diffuser Kit is designed for OEM-style installation. Both components feature pre-marked mounting points for accurate positioning and are molded to follow the factory body lines of the 997.1.
The front lip includes pre-installed 3M automotive-grade double-sided tape where applicable, along with 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 ensure proper positioning, panel alignment, secure mounting, and a clean finished appearance.
If painted, both polyurethane components require standard body-shop preparation: scuff, prime, and paint.
Appearance
The two-piece aero package provides a balanced enhancement to both ends of the Porsche 997.1. The front lip creates a lower and sharper front-end appearance, while the rear diffuser gives the back of the vehicle a more aggressive, motorsport-inspired character.
Together, the components create a cohesive exterior upgrade that increases the 997.1's road presence while maintaining its recognizable Porsche design.
Aerodynamic Performance
The front lip is designed to help manage airflow beneath the vehicle and reduce front-end lift, while the rear diffuser is designed to improve airflow separation as air exits the underside of the vehicle.
Together, these aerodynamic components are intended to provide subtle improvements in high-speed stability and a more planted driving feel without introducing unnecessary visual bulk.
Polyurethane Construction
Both components are manufactured from Better Bodies Motorsport's proprietary GT3TEK polyurethane blend. The material combines flexibility with impact resistance, allowing the aero components to flex under stress rather than behaving like rigid fiberglass.
This flexibility makes the kit particularly well suited to real-world driving conditions, including curbs, steep driveways, and minor road debris. Slight adjustment during installation can also help achieve a precise, OEM-quality fit.
Impact Resistance
Polyurethane is designed to withstand the minor impacts and contact that can occur during everyday driving. Instead of cracking or shattering like rigid fiberglass, the material can flex upon contact and return toward its original shape.
Minor contact may still result in cosmetic scuffs or scratches, which can generally be refinished during normal body-shop preparation. Front lip scrape guards are recommended for additional protection.
