Porsche 911 GT3 RS Enhanced with Manthey Racing Kit: Improved Performance and Aerodynamics

The Porsche 911 GT3 RS now comes with a Manthey Racing Kit, specially designed for improved performance on the track. Developed in partnership with Porsche, this upgrade modifies the car’s aerodynamics, suspension, and braking system to enhance handling and stability at high speeds. Despite its track-ready design, the modifications keep the car road-legal. The kit will be available globally by March 2025, distributed through Porsche Centres.

Aerodynamic upgrades: better downforce and stability

The Manthey Kit introduces significant aerodynamic improvements to the Porsche 911 GT3 RS. Key enhancements include:

Upgraded Spoilers and Wing Design: A larger front spoiler lip and reinforced rear wing provide increased stability at high speeds.
Enhanced Airflow Control: Redesigned Gurney flaps, dive planes, and six roof fins optimize airflow and improve cooling efficiency.
Lightweight Components: The rear window is replaced with a carbon-fiber panel, reducing weight by 25% and adding a shark fin for stability during cornering.

These updates generate 20% more downforce compared to the standard model, without increasing drag, ensuring better grip and control on the track.

Suspension upgrades: optimized for track handling

The kit features a semi-active suspension system designed to handle the increased aerodynamic load. Key highlights include:

Higher Spring Rates: The front suspension is stiffened by 30%, while the rear sees a 15% increase, improving response and cornering precision.
Adaptive Dampening: A new control unit processes data from multiple sensors to adjust the dampers in real-time. The shock absorbers feature dual-valve adjustments for compression and rebound, allowing for fine-tuning through driving modes like Normal, Sport, and Track.

The upgraded suspension setup ensures the car remains stable and predictable, even under demanding conditions.

Braking system: enhanced pedal response and durability

The Manthey Kit also improves braking performance, crucial for track use:

Steel-Sheathed Brake Lines: These improve pedal feedback and response for more precise braking.
Optional Racing Pads: Designed for Porsche’s Ceramic Composite Brakes, these pads offer consistent performance across varying temperatures, reducing brake fade during extended use.

These enhancements ensure the braking system complements the car’s improved aerodynamics and suspension for better overall performance.

Availability and road-legal assurance

The Manthey Racing Kit will initially be available in European markets from January 2025, with a global rollout scheduled for March 2025. Importantly, all modifications are covered under the standard Porsche warranty, ensuring peace of mind for buyers.



The Manthey Racing Kit elevates the Porsche 911 GT3 RS to new levels of track performance while keeping it practical for regular road use. For enthusiasts seeking a sharper driving experience, this upgrade represents an exciting opportunity.
