SilverRocket Dry Carbon Mini Gurney Flap & DRS-1 Rear Wing Endplate Kit – Aerodynamic Precision for Porsche 718 GT4 RS
The SilverRocket Dry Carbon Mini Gurney Flap & DRS-1 Rear Wing Endplate Kit elevates Porsche 718 GT4 RS aerodynamics to true motorsport standards. Designed for maximum performance and refined style, this lightweight kit combines aerospace-grade dry carbon fibre construction with CFD-optimised design to improve high-speed stability and downforce efficiency.

Fits:

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

The Mini Gurney Flap enhances the rear wing’s aerodynamic profile, while the DRS-1 Endplates streamline airflow across the wing edges, reducing turbulence and drag. Together, these upgrades deliver an 8.3 % increase in rear downforce at 200 km/h, ensuring superior rear-axle stability, sharper cornering, and enhanced driver confidence — both on road and track.

What Do They Do?

The kit’s components perform complementary aerodynamic functions:

Mini Gurney Flap

• Generates additional downforce by energising airflow over the wing.
  
• Improves high-speed balance and cornering stability.
  
• Increases aerodynamic grip without adding drag.

DRS-1 Endplates

• Control lateral airflow to minimise pressure loss and turbulence.
  
• Enhance downforce consistency across the entire wing span.
  
• Improve top-speed efficiency by reducing aerodynamic drag.

Why Standard Wing Components Fail

Typical plastic or composite rear-wing components degrade under heat and aerodynamic load. Failures often occur due to:

• Material fatigue or flexing during sustained high-speed use.
  
• Heat deformation and UV-related cracking.
  
• Weak structural bonding that causes vibration and air leakage.
  
• Inefficient geometry that disturbs airflow and reduces stability.

The SilverRocket kit overcomes these flaws using motorsport-grade carbon fibre layered with advanced resin bonding and a high-temperature resistant finish — guaranteeing strength, precision, and longevity even in demanding track conditions.
