Athletic TECHART Side Skirts transfer the design line to the side view.

Kit contains four pieces - two each side

The multi-piece design divides the side skirts into an inner side skirt profile which integrates seamlessly with the body and a second outer side skirt which creates a distinct contrast.
This virtually lowers the vehicle's balance point and the side skirts end with a characteristic shark-like fin in front of the rear wheel arches.

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.
