Porsche has unleashed its most extreme 911 GT3 RS upgrade package yet, partnering with Manthey Racing to create a track-focused monster that pushes the boundaries of street-legal performance. The Manthey Performance Kit transforms the already blistering GT3 RS into a circuit weapon that costs more than most luxury cars.
What Makes the Manthey Performance Kit Special
This isn’t just another cosmetic upgrade package. Manthey Racing, Porsche’s official motorsport partner and Nürburgring specialists, has developed a comprehensive aerodynamic and suspension overhaul that fundamentally changes how the GT3 RS behaves on track.
The centerpiece is a massive carbon fiber rear wing that generates significantly more downforce than the standard GT3 RS setup. Combined with an aggressive front splitter and dive planes, the package creates up to 409 pounds of additional downforce at 124 mph.
Performance Modifications Include:
- Adjustable carbon fiber rear wing with DRS-style flap
- Extended front splitter with carbon fiber dive planes
- Revised suspension geometry with track-specific alignment
- Lightweight magnesium wheels wrapped in Michelin Pilot Sport Cup 2 R tires
- Enhanced brake cooling ducts and deflectors
- Stripped interior with roll cage preparation points
Nürburgring-Proven Engineering
Manthey Racing didn’t develop this kit in isolation. Every component has been tested extensively at the Nürburgring Nordschleife, where the team holds multiple lap records and operates one of Germany’s most respected racing schools.
The suspension modifications alone required months of development work. Engineers revised the damper settings, spring rates, and anti-roll bar stiffness to work harmoniously with the increased aerodynamic load. The result is a car that maintains the GT3 RS’s street usability while delivering genuine race car dynamics on track.
Track Performance Gains
Initial testing suggests the Manthey kit shaves several seconds per lap from already impressive GT3 RS times. The additional downforce allows drivers to carry more speed through fast corners, while the enhanced cooling systems prevent brake fade during extended track sessions.
Professional drivers report significantly improved confidence at the limit, with the car providing clearer feedback about grip levels and cornering forces. The enhanced aerodynamics also improve high-speed stability, crucial for circuits with long straights.
Pricing and Availability Details
The Manthey Performance Kit carries a hefty $77,000 price tag, bringing the total cost of a fully-equipped GT3 RS to well over $300,000. Installation is only available through select Porsche Centers with Manthey Racing certification.
Porsche plans to limit production to maintain exclusivity, though exact numbers haven’t been confirmed. Early reports suggest a waiting list is already forming among serious track enthusiasts and collectors.
What’s Included in the Price
The steep cost reflects the extensive engineering and premium materials involved. Every aerodynamic component uses prepreg carbon fiber construction, while the suspension modifications require precision alignment and setup procedures that take trained technicians several days to complete properly.
Buyers also receive track day support from Manthey Racing, including setup consultation and access to exclusive driving events at European circuits.
Competition and Market Impact
This move puts Porsche directly in competition with McLaren’s MSO upgrades and Ferrari’s Assetto Fiorano packages. However, the Manthey partnership brings genuine racing pedigree that few manufacturers can match.
The kit also signals Porsche’s commitment to the naturally aspirated flat-six engine, even as the industry shifts toward electrification. By maximizing the potential of current GT3 RS technology, Porsche is creating what may become a future classic.
Track-focused supercars continue gaining popularity among enthusiasts seeking authentic performance over luxury features. The Manthey kit represents the extreme end of this trend, offering race car capability in a street-legal package.
Looking Forward
The Manthey Performance Kit arrives as Porsche prepares for its electric future, making this potentially the ultimate expression of traditional GT3 engineering. With hybrid and electric sports cars on the horizon, the enhanced GT3 RS offers purists one last chance to experience peak internal combustion performance.
Expect similar collaborations as manufacturers squeeze every ounce of performance from current technology before electrification takes over.
