Do not risk Pentosin® Power Steering fluid leaks into your engine bay or down the bumper. Extensively designed and engineered to permanently fix the overly complex and troublesome factory hydraulic mechanism. Since 2015, our eRam Kit™ is the best permanent economical solution to maintain a fully functional wing!
The dealer wants up to £1000's to replace a troublesome hydraulic mechanism. Others offer a rebuild service, simply tearing down and repairing the same failure prone mechanism, often using solvents to swell internal o-rings. Another offers shiny aftermarket parts for the internal hydraulic mechanism made from stainless instead of brass. They do not even attempt to call it a permanent solution, claiming it is "easy" to change out cheap internal o-rings to refill and bleed the mechanism when it fails again… Who wants to go through that EVER let alone more than once? It is only a matter of time until hot engine bay conditions destroy one of many hydraulic components that are failure prone!
The eRam Kit™ wing elevator consists of two pre-assembled self-contained electric Rams that simply bolt onto the engine lid with absolutely NO modifications. The eRam Kit™ includes a small electronic "MicroModule Device™" that connects to the factory wiring and prevents the dreaded SPOILER WARNING. Nearly plug and play! WORKS EXACTLY LIKE THE FACTORY MECHANISM.
The patented eRam Kit™ comes with two self-contained electric eRams, all fittings, fasteners, electrical connections, and the tiny MicroModule Device™ which prevents the spoiler warning. No cutting, drilling or modification to any part of the car. Easy install – about the same skill level as changing brake pads. Installation of the eRam Kit™ takes about 2 hours for anyone with any mechanical skill. Most customers install the eRam Kit™ themselves using our illustrated instruction guide and video (sent with purchase). Easily maintained – no special tools needed. Easily modified – for example to exchange for different length rams or to add Dust & Moisture Boots.

The rear spoiler rubber wall acts as a flexible sealing barrier between the spoiler assembly and the engine-lid area. It prevents the ingress of dirt, dust, and water into the rear deck, while helping to maintain proper airflow and cooling efficiency around the spoiler and engine bay. In addition, it provides a clean, factory-finished appearance and protects nearby trim panels from rubbing or wear.

The rubber wall insert (also referred to as the “spoiler-rubber wall” or rear deck spoiler barrier) is designed for the rear spoiler assembly on Porsche 911 model generations 996 and 997. This insert sits behind the rear spoiler assembly (on the rear deck/engine-lid area) and creates a flexible barrier between the spoiler structure and the bodywork - helping protect paintwork, reduce turbulence, control debris ingress and maintain factory appearance. Please note you may also require new clips order 2x part number 99959171240.

• Position on Vehicle: Rear deck area, behind the spoiler or on the spoiler mounting surface, between the spoiler and body panel.
• Function: Acts as a sealed and resilient joiner between the spoiler and body, reducing noise, preventing water‐ and debris penetration under the spoiler, preserving rear-deck finish and supporting correct aerodynamic/turbulence behaviour.
• Applications: Ideal when the original spoiler rubber insert is missing, degraded, cracked, hardened, or causing wind noise, ingress, or aesthetic deterioration.
Even minor trim components like this rubber wall insert play a significant role in the vehicle’s appearance and function. Worn or missing inserts can lead to:
• Wind noise, ripple or vibration behind the spoiler
• Water or dust intrusion under the spoiler, risking corrosion or paint damage
• Poor fitment or mismatched gap between spoiler and body
• Degraded aerodynamic behaviour or unwanted turbulence

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.
