The UCW rear wing is a great addition to your 991 GT3 to significantly increase downforce at the rear, increase confidence on track, and reduce lap times.
Verus Engineering developed the UCW rear wing to bridge the gap between our swan neck high-efficiency rear wing and our 300mm V1X airfoil. With the 250mm curved chord, the UCW makes more downforce than the high-efficiency rear wing and significantly more downforce than similarly sized competitor wings.
Utilizing state-of-the-art analysis software during the R&D process, we optimized the airfoil for performance for the given build volume which is derived from the V1X. Further utilizing CFD, we ensured the rear wing sees adequate airflow while installed and performs well.
During the design process; we utilised in-house scan data. This results in a product that features a near OEM fit and finish.
The UCW wing is the perfect addition to the track goer who requires a large bump in rear downforce to balance out a significant front aero package.

Porsche Rear Spoilers & Aerofoils | Performance, Stability & Design Enhancement
Rear spoilers and aerofoils are key aerodynamic components designed to increase downforce, improve stability, and enhance the distinctive styling of your Porsche. Whether you’re replacing a damaged spoiler, upgrading to a lightweight performance aerofoil, or transforming your vehicle’s exterior for a sportier stance, these parts combine aerodynamic precision with visual appeal.
At Design911, we supply a comprehensive range of high-quality rear spoilers and aerofoils, crafted from advanced materials such as carbon fibre, fiberglass, and composite alloys for maximum strength and minimal weight. Designed for precision fitment, these components deliver improved handling, reduced lift, and a more aggressive aesthetic that reflects Porsche’s racing heritage.
Suitable for classic 911s through to modern 992, Cayman, and Boxster models, our rear spoilers ensure a perfect balance of performance, design, and durability for every application — from restoration to motorsport preparation.
What Do Rear Spoilers and Aerofoils Do?
A rear spoiler or aerofoil manages airflow over your Porsche’s body to enhance stability, grip, and aerodynamic efficiency. By reducing lift and increasing rear downforce, it ensures consistent traction and improved high-speed performance.
Core Functions:
- Increases
rear downforce for enhanced stability and control.
- Reduces
aerodynamic lift and drag at high speeds.
- Improves
traction during cornering and acceleration.
- Directs
airflow for better cooling efficiency.
- Adds a distinctive motorsport-inspired aesthetic.
A well-engineered spoiler doesn’t just look stunning — it directly contributes to safer, more predictable handling and optimal balance under load.
Why Do Rear Spoilers and Aerofoils Fail or Deteriorate?
Rear spoilers are exposed to aerodynamic pressure, vibration, and environmental conditions, which can lead to wear and damage over time.
Common Causes of Failure Include:
- UV
degradation leading to fading or cracking of materials.
- Impact
damage from debris or rear-end collisions.
- Corrosion
or fatigue in metal mounting brackets.
- Loose
fittings causing vibration or misalignment.
- Paint wear or delamination on carbon fibre surfaces.
If neglected, a damaged or unstable spoiler can cause aerodynamic imbalance, increased drag, and even safety concerns at higher speeds — making timely replacement or upgrade essential.
Why Replace Your Rear Spoiler or Aerofoil?
Replacing a worn or damaged rear spoiler ensures aerodynamic integrity and restores your Porsche’s original performance and appearance. Upgrading to a modern or motorsport-style aerofoil can further enhance downforce, aesthetics, and handling precision.
Key Benefits:
- Restores
aerodynamic balance and rear stability.
- Improves
cornering grip and high-speed control.
- Enhances
vehicle appearance with performance styling.
- Lightweight
materials for improved performance efficiency.
- Precision-engineered for seamless installation.
- Ideal for restoration or track-focused upgrades.
Whether you prefer a classic ducktail design, GT-style rear wing, or a carbon fibre adjustable aerofoil, our range of Porsche rear spoilers ensures you achieve the perfect blend of heritage and performance.
Highlights:
- Premium Porsche rear spoilers and aerofoils for all models.
- Engineered for aerodynamic performance and design accuracy.
- Lightweight carbon fibre, fiberglass, or composite construction.
- Direct-fit replacement or upgrade options available.
- Ideal for both street and track applications.
- Restores performance while elevating exterior styling.
