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
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.
- CFD-optimised
design for precision
airflow management.
- Heat
and UV-resistant finish
ensures long-term durability.
- Enhanced
visual appeal with
exposed dry carbon fibre weave.
- Perfect fitment and alignment, designed for direct installation on Porsche 718 GT4 RS.
These upgrades are designed for performance enthusiasts,
track-day drivers, and those who demand motorsport precision with refined
styling.
Highlights:
- 8.3%
increase in rear downforce at 200 km/h, delivering measurable aerodynamic gains.
- Dry
carbon fibre construction
that’s 50% lighter than manufacturer-standard alternatives.
- Motorsport-grade
weave and resin composition for maximum strength and rigidity.
- CFD-engineered
and track-tested for
superior airflow control.
- Sleek,
exposed carbon aesthetic
complements Porsche’s GT design language.
- Precision mounting design ensures easy installation and perfect aerodynamic alignment.
