When paired with SilverRocket’s DRS-1 Dry Carbon Rear Wing Endplates, the Mini Gurney Flap delivers an 8.3% increase in rear downforce at 200 km/h, resulting in greater high-speed stability, enhanced grip, and improved aerodynamic balance — without adding drag.
This subtle yet powerful upgrade enhances the sporty profile of the GT4 RS’s standard rear wing, giving it a more aggressive track-ready appearance while delivering measurable aerodynamic gains.
What Does a Mini Gurney Flap
Do?
A gurney flap is a small aerodynamic tab mounted along the
trailing edge of a wing. Though compact, it plays a vital role in increasing
downforce by modifying airflow and pressure distribution over the rear
wing.
Core Functions:
- Increases rear downforce by energising airflow over the wing surface.
- Improves high-speed stability and cornering control.
- Enhances braking performance by maintaining rear-end grip.
- Balances aerodynamic load, ensuring predictable handling at speed.
The SilverRocket Mini Gurney Flap is designed to complement Porsche’s GT aerodynamics, adding measurable aerodynamic benefit with race-inspired precision.
Why Do Standard or Aftermarket Gurney Flaps Fail?
Over time, lower-grade or poorly designed gurney flaps can
lose structural integrity and aerodynamic precision. Common causes of failure
include:
- Material
fatigue from constant aerodynamic load.
- UV
or heat damage causing warping or delamination.
- Weak
mounting surfaces leading to vibration or instability.
- Poor aerodynamic profiling that increases drag rather than reducing it.
The SilverRocket Mini Gurney Flap overcomes these issues through motorsport-grade carbon fibre construction, precision machining, and a heat-resistant resin system, guaranteeing durability and consistent aerodynamic performance.

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.
