997 Mach ll side skirts rocker panels 2005-2012 Carrera/GT3 Narrow Body

How Easy is it to Install?
The BetterBodies Motorsport Porsche 997 Mach II Side Skirts / Rocker Panels are designed for OEM-style fitment, perfectly aligning with the 2005–2012 Porsche 997 Carrera, Carrera S, Carrera 4, Carrera 4S, and GT3 narrow-body models. Each skirt is molded with pre-marked mounting points for accurate placement and includes pre-installed 3M automotive-grade double-sided tape along with the necessary mounting hardware for a secure installation. Constructed from premium polyurethane, these skirts arrive in a raw black finish and require standard body shop prep (scuff, prime, paint) if you wish to color match them to your Porsche. While skilled DIY installers can complete the installation, we recommend professional fitting to ensure perfect alignment and finish. If in stock, these ship within 24–48 hours; if backordered, please allow 3–8 business days for dispatch.

Appearance
The Mach II design offers a sleeker and more streamlined alternative to boxier factory-style rockers. These side skirts subtly elongate the car’s profile, creating a lower, more aggressive stance without overpowering the 997’s natural curves. Perfect for pairing with a front lip and rear diffuser, they complete the car’s side profile for a cohesive, motorsport-inspired look that works equally well on street builds and track setups.

What is Polyurethane?
Manufactured from our proprietary GT3TEK polyurethane blend, these rocker panels combine long-term durability with exceptional flexibility. Unlike fiberglass or ABS plastic, polyurethane can flex under stress and return to its original form, making it highly resistant to cracks, chips, or breakage. This flexibility also makes them easier to install and adjust for OEM-quality fitment.

Performance Capabilities
While primarily a visual upgrade, the aerodynamic contour of these Mach II side skirts helps manage airflow along the car’s flanks, reducing turbulence and improving high-speed stability. When paired with complementary front and rear aero upgrades, they contribute to a more balanced aerodynamic profile.

Will it Crack or Break?
ABSOLUTELY NOT - Polyurethane is built for real-world driving conditions. These side skirts can flex when encountering curbs, steep driveways, or road debris, then return to their original shape without structural damage. Most impacts leave only minor cosmetic marks that can be refinished if desired.
