Carbon Fibre Side Sill Set – Sold as a Pair

Upgrade the side profile of your Porsche 911 992 GT3 or GT3 Touring with the SFORZA Carbon Fibre Side Sill Set, manufactured in Italy from high-quality pre-preg carbon fibre.

Fits:

  • Porsche 992.1 GT3 4.0L / 992 S/T 4.0L 2021-24
  • Porsche 992.1 Touring 4.0L 2021-24
  • Porsche 992.2 GT3 2025>>

Supplied as a left and right-hand pair, these carbon fibre side skirts directly replace the existing side sills, providing an OEM-style fit while adding the distinctive appearance of exposed carbon fibre.

Designed for both first and second-generation 992 GT3 models, including the GT3 Touring, they are an ideal upgrade for owners looking to introduce additional carbon fibre detailing while retaining the original lines of the car.

Pre-Preg Autoclave Carbon Fibre Construction

The SFORZA side sills are manufactured from 2x2 twill 200gsm pre-preg carbon fibre using an autoclave moulding process.

During manufacture, the carbon fibre is cured under controlled high temperature and pressure. This production method provides excellent strength, consistency and surface quality while allowing the components to remain lightweight.

The visible 2x2 twill carbon weave provides the high-quality motorsport-inspired appearance expected from a premium carbon fibre upgrade.

Gloss Clear Coat Finish

Each side sill is finished with a gloss clear coat that highlights the carbon fibre weave while providing a smooth, premium appearance.

The gloss finish complements other exposed carbon fibre components fitted to the 992 GT3 and provides a more distinctive appearance compared with the standard side skirts.

Direct Replacement Installation

The SFORZA carbon fibre side sills are designed as replacements for the existing factory side skirts rather than covers fitted over the original components.

Their OEM-style fit allows them to integrate neatly with the original bodywork and retain the distinctive profile of the 992 GT3.

Material
 2x2 twill 200gsm pre-preg carbon fibre, autoclave moulded.

Finish
 Gloss clear coat.

Country of Manufacture
 Italy (EU)

Porsche 992 GT3 & GT3 Touring Carbon Fibre Side Skirts

Designed for both 992 GT3 and GT3 Touring models, including MK1 and MK2 versions, the exposed 2x2 twill weave provides a distinctive motorsport-inspired finish without compromising the original body design.

About Side Sill Trims / Skirts

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.

Key Benefits:

  • Improves aerodynamic stability and efficiency.
  • Protects lower panels from dirt and impact damage.
  • Enhances the visual profile with a performance-inspired look.
  • Lightweight construction for better performance.
  • Precision fitment for easy installation and secure mounting.
  • Available in various finishes — gloss black, carbon fibre, or body-coloured.

Ideal for both track-focused builds and street-driven upgrades, these parts provide the perfect combination of functionality, performance, and style.

Highlights:

  • Premium Porsche side sill trims and skirts.
  • Aerodynamically tested designs for improved stability.
  • Durable materials like carbon fibre and composite blends.
  • Direct-fit replacements for Porsche 911, Cayman, Boxster, Taycan and more.
  • Restores protection and enhances styling. Perfect for performance or restoration projects.
