996 Rockers + Lip + Small Ducktail + Diffuser

How Easy is it to Install?
The BetterBodies Motorsport Porsche 911 996.1 & 996.2 Rockers + Lip + Small Ducktail + Diffuser Kit is designed for precise OEM-style fitment, with each component molded to match the exact body lines of both the 996.1 (1999–2001) and 996.2 (2002–2004) generations. Each part features pre-marked mounting points for straightforward alignment, and most components include pre-installed 3M automotive-grade double-sided tape along with the necessary mounting hardware. All polyurethane parts will require standard body shop prep (scuff, prime, paint) if you choose to color match to your Porsche. Confident DIY installers can fit the kit, but for the best results—especially with paint work—professional installation is recommended. If the kit is in stock, it ships within 24–48 hours; if on backorder, please allow 3–8 business days for dispatch.

Appearance
This complete aero kit brings a refined yet aggressive transformation to the Porsche 996, enhancing its profile from every angle. The front lip lowers and sharpens the car’s stance, the side rockers visually extend the body for a more planted appearance, the small ducktail spoiler adds a subtle nod to Porsche’s motorsport heritage without overwhelming the rear, and the diffuser completes the look with a modern performance edge. The result is a cohesive, track-inspired style that balances classic Porsche elegance with contemporary aggression.

What is Polyurethane?
Our proprietary GT3TEK polyurethane blend offers the perfect combination of durability and flexibility. Unlike fiberglass or ABS plastic, it can flex under stress and return to its original shape, making it far more resistant to cracking, chipping, or breaking. This flexibility not only ensures better long-term performance but also makes installation and alignment easier. It’s a material built for the real world, capable of handling daily driving, spirited runs, and even minor contact with road debris or steep driveways.

Performance Capabilities
Beyond its visual upgrades, this kit offers tangible performance benefits. The front lip helps direct airflow, reducing lift at higher speeds, while the diffuser improves rear-end airflow separation for a cleaner aerodynamic profile. The small ducktail spoiler provides subtle downforce without excessive drag, and the side rockers help channel air smoothly along the car’s sides. Together, these enhancements contribute to improved stability and a more confident feel behind the wheel, whether on the street or at the track.

Will it Crack or Break?
ABSOLUTELY NOT - Polyurethane is highly resistant to damage compared to brittle alternatives. It’s designed to flex and absorb minor impacts, such as those from steep driveways or road debris, without cracking. In most cases, it will return to its original shape, with only cosmetic touch-ups needed after heavier contact. Adding scrape guards can provide extra protection for the front lip in high-contact situations.
