Carbon Fibre Side Sill Set – Sold as a Pair
Give your Porsche 911 992 a more aggressive GT3-inspired appearance with the SFORZA GT3-Style Carbon Fibre Side Skirt Set.
Designed for Porsche 992 Carrera, Carrera S, Carrera T, Carrera 4S, Targa and GTS models, these side skirts directly replace the original factory components, adding a distinctive motorsport-inspired look to the lower profile of the car.
Manufactured from pre-preg carbon fibre and autoclave cured at high temperature and pressure, they combine lightweight construction with a premium exposed carbon fibre finish.
GT3-Inspired Styling
Inspired by the purposeful appearance of the 992 GT3, these side skirts give Carrera and Targa models a more performance-focused look.
Their sculpted profile emphasises the 992's aerodynamic body shape and visually lowers the sides of the car, making them particularly effective when combined with other GT3-style or carbon fibre exterior upgrades.
Pre-Preg Autoclave Carbon Fibre
SFORZA manufactures the side skirts from high-quality pre-preg carbon fibre using an autoclave curing process.
The carbon is cured under controlled high temperature and pressure, producing a lightweight, strong and consistent component with the premium surface quality expected from a high-end carbon fibre upgrade.
Gloss Carbon Fibre Finish
The exposed carbon fibre weave is finished with a glossy clear coat, highlighting the depth and pattern of the carbon.
This finish complements other gloss carbon components fitted to the Porsche 992, including front spoilers, rear diffusers, mirror trim and aerodynamic components.
Direct Replacement Installation
The SFORZA side skirts are designed as direct replacements for the original factory side skirts rather than covers fitted over the existing components.
They utilise the existing factory mounting points and hardware, allowing installation without cutting, drilling or other permanent modifications.

Porsche Side Sill Trims & Skirts | Aerodynamic Design with Style and Function
Side sill trims and skirts are essential components of your Porsche’s exterior design, providing both aerodynamic efficiency and a refined, sporty look. These panels streamline airflow along the vehicle’s sides, reduce drag, and enhance stability at higher speeds — all while protecting the lower bodywork from debris and road wear.
At Design911, we supply a wide range of high-quality side sill trims and skirts made from lightweight materials such as carbon fibre, fiberglass, and reinforced composites. Precision-moulded for perfect fitment, these components deliver superior durability and finish — whether you’re refreshing worn trims, upgrading for a sportier stance, or completing a full body conversion.
From classic 911 models to modern Cayman, Boxster, and Taycan variants, our side skirts combine performance styling with lasting protection, offering the ideal solution for enthusiasts seeking motorsport-inspired design with everyday practicality.
What Do Side Sill Trims and Skirts Do?
Side sill trims and skirts improve the aerodynamic profile of your Porsche while adding visual balance to the car’s exterior.
Core Functions:
Direct airflow along
the car’s sides to reduce drag and turbulence.
Enhance aerodynamic efficiency and
improve vehicle stability.
Protect lower body panels from
stones, mud, and debris.
Visually lower the vehicle’s profile for a sportier, more aggressive stance.
Complement front and rear spoilers for a cohesive aerodynamic setup.
Properly fitted side skirts can reduce lift, increase stability, and add a distinctive, performance-oriented character to your Porsche.
Why Do Side Sill Trims and Skirts Fail or Degrade?
While designed for durability, side trims are constantly exposed to environmental and physical stresses that can cause wear or damage over time.
Common Causes of Failure Include:
- Impact damage from curbs or road debris.
- Cracking or chipping from age or stress.
- UV exposure leading to discoloration or fading.
- Corrosion or fatigue in mounting points or fasteners.
- Improper installation causing misalignment or vibration.
Damaged side skirts can disrupt airflow, reduce aerodynamic efficiency, and detract from your Porsche’s clean, streamlined appearance — making repair or replacement essential for performance and aesthetics.
Why Replace or Upgrade Your Porsche Side Sill Trims or Skirts?
Upgrading or replacing your Porsche’s side sill trims restores both aerodynamic balance and design integrity, ensuring your vehicle performs and looks its best.

- Improves aerodynamic stability and efficiency.
- Protects lower panels from dirt and impact damage.
