Porsche 911 (991 / 991.2, 2012-2019) Prepreg Dry Carbon Fiber Side Skirt — V2 Aggressive

Engineered for Porsche 911 991 / 991.2 owners, this European-made Prepreg (Dry) Carbon Fiber Side Skirt V2 is our second 991 side skirt design — a deeper, more aggressive, motorsport-inspired carbon rocker. Quality-controlled by BYC Performance, this Porsche 911 carbon side skirt v2 bolts directly to OEM mounting points. Compared to our OEM-style 991 side skirt, this V2 is noticeably deeper, more curved, and aero-focused.

The deeper rocker curve and extended lower edge channel wheel-arch airflow more aggressively toward the rear diffuser. The integrated edge blade underneath draws from 911 GT3 R / Cup race-car practice. The same rocker geometry is shared across all Carrera Coupé trims from the 991.1 Carrera 3.4L NA to the 991.2 GT3 4.0L NA 500 hp. For a cleaner street-oriented alternative see our first 991 side skirt variant.

Prepreg (Dry) Carbon vs. Wet Carbon — Which Is Better?

Most aftermarket carbon parts are made using wet lay-up, with hand-applied resin cured at room temperature. Prepreg (dry) carbon:

• Cured in an autoclave under high heat and pressure → a more consistent weave
• A controlled resin ratio → lighter and stronger
• The production method widely chosen in motorsport
• Minimal UV fading over years of use
