The Porsche 911 GT3 has long been considered one of the most pure and engaging performance cars ever built. Yet in the hands of Manthey, Porsche’s long-time motorsport partner, the GT3 reaches an entirely new level. The Manthey Kit transforms the already spectacular 911 GT3 into a sharper, faster, more focused machine — engineered for drivers who demand uncompromising track performance without sacrificing road legality.
Aerodynamic Engineering That Redefines the GT3
The Manthey Kit elevates the GT3’s aerodynamics with a complete rethink of airflow and downforce. The redesigned front section includes a deeper splitter, extended air deflectors and refined side flaps that guide airflow with greater efficiency. Underneath, a more aggressive underbody layout stabilizes the car at high speeds.
At the rear, a wider wing with enhanced adjustability, a pronounced Gurney flap and a larger diffuser work together to significantly increase aerodynamic grip. Rear wheel aerodiscs complete the functional racing aesthetic while smoothing airflow in high-speed corners.
In its maximum-performance configuration, the Manthey-enhanced GT3 delivers dramatically increased downforce, translating into enhanced stability, faster cornering and improved braking zones — essential traits for track-focused driving.
Chassis and Suspension: Precision You Can Feel
Manthey’s upgrades continue beneath the bodywork. The suspension receives a bespoke coilover system with four-way adjustability, allowing fine control over compression and rebound. These settings enable drivers to tailor the car precisely to circuit conditions, personal driving style or tyre choice.
Stiffer spring rates and optimized damping deliver more confidence at speed, particularly under heavy aerodynamic load. The optional lightweight forged wheels further reduce unsprung mass, improving responsiveness and road feedback.
The braking system benefits from braided steel lines and optional motorsport-inspired pads, offering enhanced durability and sharper pedal feel during repeated high-frequency braking.

Performance You Can Trust on Road and Track
Despite the extensive upgrades, the Manthey Kit maintains the GT3’s dual-use nature. It remains perfectly capable of everyday road driving, while unleashing its full potential on track days. The naturally aspirated flat-six remains untouched — a testament to Porsche’s already impeccable powertrain — yet the improved aerodynamics and chassis tuning allow the GT3 to deliver a more controlled, precise and confidence-filled performance experience.
Drivers benefit from:
- sharper turn-in
- increased stability in fast corners
- reduced lap times thanks to improved grip
- superior braking consistency during long sessions
It feels like a GT3 refined through thousands of racing-focused decisions.
Design That Reflects Capability
Visually, the Manthey Kit adds an unmistakable level of purpose. The aerodynamic components, carbon-fiber details, wider stance and optional forged wheels give the car a more aggressive posture. Function dictates form — and every added element expresses performance intent.
Owners also gain access to Manthey Racing’s wider catalogue of accessories, offering the opportunity to personalize and elevate their GT3 even further.
Why Enthusiasts Choose the Manthey Version
The Manthey-equipped GT3 is far more than an aftermarket upgrade. It represents:
- racing-derived engineering refined for road use
- factory-approved components with OEM quality
- significant aerodynamic and handling advantages
- track-validated performance improvements
- a unique identity for drivers who want the ultimate evolution of the GT3
For many enthusiasts, this is the closest you can get to a road-legal GT3 Cup experience.
A Masterpiece of Track-Focused Engineering
The Porsche 911 GT3 is already an icon — but the Manthey Kit elevates it into a different category. It is sharper, more stable, more capable and more rewarding for those who truly understand the language of racing. The kit doesn’t change the character of the GT3; it amplifies it.
For drivers seeking the pinnacle of GT3 performance, supported by motorsport-proven engineering and track-validated results, the Manthey-enhanced 911 stands as the ultimate expression of the model.
