SilverRocket DRS-1 Dry Carbon Fibre Rear Wing Endplates – Advanced Aerodynamics for Porsche 718 GT4 RS
The SilverRocket DRS-1 Dry Carbon Fibre Rear Wing Endplates redefine aerodynamic performance and visual precision for the Porsche 718 GT4 RS. Designed for drivers seeking both speed and stability, these endplates are engineered from aerospace-grade dry carbon fibre, delivering a 50% weight reduction compared to standard plastic alternatives while improving aerodynamic efficiency and structural rigidity.

Fits:

• Porsche Cayman GT4 718 4.0L / GT4 RS 718 4.0L
• Porsche Cayman GT4 RS Clubsport 2020-2024
  
  

FOR OEM REAR WING ONLY

Paired with the SilverRocket mini gurney flap, the DRS-1 endplates generate an 8.3% increase in rear downforce at 200 km/h, resulting in enhanced high-speed balance, improved cornering grip, and a more planted feel during aggressive driving or track sessions.

Developed through Computational Fluid Dynamics (CFD) simulation and verified through wind tunnel testing, these endplates exemplify SilverRocket’s commitment to precision-engineered, motorsport-grade performance parts for Porsche GT applications.

What Do Rear Wing Endplates Do?
Rear wing endplates are critical components that shape how air flows over and around the rear wing. Their primary function is to manage airflow efficiency and maintain aerodynamic stability.

Core Functions:

• Increase rear downforce by containing airflow across the wing surface.
  
• Reduce drag and turbulence created by high-speed air separation.
  
• Stabilise vehicle balance during cornering and braking.
  
• Improve aerodynamic consistency, optimising handling and traction.

By refining airflow and limiting lateral air escape, the DRS-1 endplates help your GT4 RS maintain high-speed stability, improving both lap times and driver confidence.

Why Do Rear Wing Endplates Fail?

Over time, standard plastic or composite endplates degrade due to the extreme aerodynamic and thermal stresses placed on them during performance driving. Common issues include:

• Cracking or fatigue from high-speed aerodynamic loads.
  
• Material flex that reduces downforce effectiveness.
  
• UV damage and heat deformation, compromising structural integrity.
  
• Loose mounting points from vibration or impact.

SilverRocket’s dry carbon fibre construction eliminates these weaknesses by offering unmatched stiffness, lower weight, and superior heat resistance, ensuring long-term reliability and consistent aerodynamic performance.

Why Upgrade to SilverRocket DRS-1 Dry Carbon Fibre Endplates?
The DRS-1 endplates are not just lighter — they’re smarter, stronger, and more aerodynamically efficient. Using motorsport-grade carbon weave and advanced resin bonding, these components enhance your GT4 RS’s performance and appearance.

Key Benefits:
8.3% increase in rear downforce at 200 km/h (with the SilverRocket mini gurney flap).

• 50% lighter than standard plastic endplates.
  
• Improved high-speed stability and aerodynamic balance.

Eliminate the risk of metal dents when using high downforce AOA (angle of attack) settings or bigger rear wings

When the GT4RS operates with high downforce AOA angles settings on high-speed tracks, or when utilising high downforce motorsport wings, the potential for metal dents increases. For instance, the SilverRocket DRS-1 wing can generate over 250 kg of downforce at 200MPH Speed. This substantial downforce is supported by the car's body through the wing support.

If the left and right supporting anchors are not adjusted evenly, there is a risk that the high downforce could cause dents in the metal at the supporting points.

Highlights:

Benefit: Eliminate the risk of metal dents with High-downforce AOA (angle of attack) settings & bigger wings.
Material: Crafted from 100% aerospace-grade dry carbon fiber, twice the strength of steel.
Installation: Pre-fitted with 3M VHB tape for quick and easy installation in just 30 seconds.

TechArt Rear Spoiler Supports.

Fits:
Porsche 718 Cayman GT4 / GT4 RS

Aerodynamic upgrade and uncompromising motorsports styling. The black anodized TECHART rear spoiler supports for the 718 Cayman GT4 raise the level of the rear wing by 40 mm and enable a multi-step angle adjustment of the wing profile.
