997.1 Lip + Diffuser

How Easy is it to Install?
The BetterBodies Motorsport Porsche 911 997.1 Lip + Diffuser Kit is designed for OEM-style fitment, with both components molded to match the precise factory body lines of the 2005–2008 997.1 generation. Each part features pre-marked mounting points for accurate positioning. The front lip includes pre-installed 3M automotive-grade double-sided tape and the necessary mounting hardware for secure attachment, while the rear diffuser is designed to integrate directly with the factory bumper’s mounting locations. All polyurethane parts require standard body shop prep (scuff, prime, paint) if you plan to color match them to your Porsche. While confident DIY installers can complete the process, we recommend professional installation to ensure proper alignment and a flawless finish. If the kit is in stock, it will ship within 24–48 hours; if backordered, please allow 3–8 business days for dispatch.

Appearance
This two-piece aero kit delivers a performance-focused enhancement to both the front and rear of the Porsche 997.1. The front lip lowers and sharpens the car’s nose, creating a more aggressive stance, while the rear diffuser adds a motorsport-inspired touch to the back end. Together, they form a cohesive upgrade that elevates the vehicle’s road presence without overshadowing its timeless Porsche styling.

What is Polyurethane?
Both parts are crafted from our proprietary GT3TEK polyurethane blend, providing the ideal balance of durability and flexibility. Unlike fiberglass or ABS plastic, polyurethane can flex under stress and return to its original shape, making it highly resistant to cracks, chips, and breakage. This flexibility also simplifies installation, allowing for slight adjustments to achieve OEM-quality fitment.

Performance Capabilities
Beyond visual appeal, these parts contribute to subtle aerodynamic improvements. The front lip helps reduce lift by managing airflow under the car, while the diffuser enhances rear airflow separation for improved stability at speed. Together, they provide a more planted, confidence-inspiring driving experience without increasing drag.

Will it Crack or Break?
ABSOLUTELY NOT - Polyurethane is impact-resistant and well-suited for real-world driving conditions. It flexes upon contact with curbs, steep driveways, or road debris, then returns to its original form. Most impacts leave only minor cosmetic marks, which can be refinished if desired. Scrape guards for the front lip are recommended for additional protection.
