Disc – Porsche Motorsport Aerodynamics Reinvented for the Modern GT
Sold as a Pair
The SilverRocket Front Wheel Dry Carbon Fibre Turbofan
Aero Disc revives one of Porsche’s most revolutionary motorsport
innovations — the turbofan wheel design — and integrates it into the
modern Porsche 718 GT4 RS. Precision-engineered using aerospace-grade
dry carbon fibre and a race-ready heat-resistant (R-HR) coating, the
AeroDisc enhances aerodynamic performance, optimises brake cooling, and
increases front axle downforce — all while elevating the visual presence of
your GT4 RS.
Fits:
Only for Aluminium wheels
Inspired by the Porsche 917/30 that dominated the 1973 Can-Am series, this advanced turbofan system channels SilverRocket’s engineering excellence and modern AI-driven aerodynamic design to deliver real performance gains on track.
What Does the SilverRocket Turbofan Aero Disc Do?
The SilverRocket AeroDisc isn’t just a styling enhancement — it’s a functional aerodynamic upgrade that improves performance where it matters most.
Core Functions:
- Enhances
brake cooling: The integrated turbofan blades act as centrifugal
pumps, evacuating hot air from the brake system and maintaining optimal
disc temperature.
- Increases
drag-free downforce on the front axle: The airflow redirection
stabilises the car at high speeds without additional drag.
- Reduces
aerodynamic drag: Smooth outer surfaces streamline wheel airflow for
higher top speed and improved balance.
- Improves lap times: Proven through extensive track testing, the AeroDisc Pro increases top speed by 14 km/h (8.7 mph) when combined with SilverRocket’s rear AeroDisc system.
These discs are specifically engineered to fit Porsche 718 GT4 RS with OEM aluminium wheels, ensuring a perfect, balanced fit and seamless aerodynamic integration.
The Evolution of
Porsche Turbofan Aerodynamics
The turbofan aero disc concept originated in Porsche’s
917/30 — the most powerful road racing car of its era. Facing extreme brake
heat (up to 700°C/1,290°F), Porsche engineers devised radial-blade turbofans
that expelled hot air from the wheel wells via centrifugal force.
Though later banned from regulated racing for being “movable aerodynamic devices,” this innovation continues to influence Porsche’s engineering philosophy. SilverRocket brings it back with 21st-century advancements, combining heritage design with modern carbon fibre craftsmanship and AI-driven Computational Fluid Dynamics (CFD) optimisation.
Why Do Traditional Aero Discs Fail?
Conventional aluminium or composite aero discs often
underperform due to:
- Heat
fatigue and deformation under high brake temperatures.
- Poor
airflow management from outdated blade geometry.
- Excessive
weight, negatively impacting unsprung mass.
- Surface delamination or warping during prolonged use.
SilverRocket solves these issues with AI-designed high-efficiency turbofan blades and a 0.5 mm Race-Ready Heat-Resistant (R-HR) coating that shields against extreme brake heat — proven to withstand over 500°F in professional track environments.
Why Upgrade to SilverRocket’s Carbon Fibre Aero Disc?
Upgrading to SilverRocket’s Front Wheel Turbofan Aero Disc delivers tangible benefits in both performance and engineering precision.
Key Advantages:
- Brake
cooling efficiency: Peak brake disc temperatures reduced from 585°C to
