Pre-preg "Dry" Carbon Fibre
Dry carbon fibre fabric is weaved with resin pre-impregnated carbon fibre (called “pre-preg” in carbon fibre industry)
Pre-preg carbon fibre reaches optimal resin/carbon ratio to strive for its characteristics, thus during the carbon parts manufacturing process, there is no resin application needed when moulding. This is why it is called “Dry” carbon fibre.
The autoclave process is another important step to finish our products. In the autoclave, the high pressure and temperature are the key to our products’ tensile strength, which can be up to 15 times higher than steel.
Unlike the Wet carbon fibre where the resin is applied into carbon fibre cloth to form a sturdy structure, dry carbon fibre parts are generally 50-60% lighter than those made of wet carbon fibre and the strength of these two materials are also different.
Another thing that is hard to overlook is the finish, dry carbon creates a beautiful & clean weave in the autoclave while wet carbon comes out to be otherwise. Even average dry carbon is way better than wet carbon in looks, strength and weight.
Dry Carbon Fibre
• Clean weave, better look/finish
• Significantly stronger & more durable
• 50-60% lighter than wet carbon

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?
