When Porsche collaborates with renowned circuit specialist Manthey Racing, the outcome pushes motorsport boundaries to unprecedented levels. The German manufacturer has unveiled the most extreme 911 GT3 ever created, incorporating a comprehensive performance kit that transforms this already formidable sports car into a track-focused weapon. This partnership delivers an engineering masterpiece that achieved a staggering 7 :12 lap time around the legendary Nürburgring Nordschleife, setting a new benchmark for production-based performance vehicles. The enhancement package maintains full road homologation while offering modifications that rival professional racing specifications, proving that street-legal cars can deliver competition-level performance without compromising manufacturer warranty coverage.
Record-breaking performance that redefines circuit capability
The Manthey-enhanced GT3 demonstrates exceptional prowess on the Nordschleife circuit, where decades of motorsport heritage converge with cutting-edge aerodynamic development. Engineers spent countless hours refining every aspect of the vehicle’s track performance, resulting in modifications that elevate downforce generation to extraordinary levels. At 285 km/h, the enhanced configuration produces 540 kg of aerodynamic load, compared to 355 kg in standard specification—a remarkable increase that fundamentally alters high-speed stability and cornering potential.
This radical transformation stems from comprehensive aerodynamic redesign encompassing multiple vehicle systems. The complete undertray creates a sophisticated diffusion channel, while revised front splitter, lateral flaps, and optimized rear diffuser work synergistically to manage airflow with precision typically reserved for endurance racing machinery. The rear wing receives particular attention, featuring increased dimensions and ultimate custom upgrade elements including a pronounced trailing edge inspired by GT competition requirements. Even wheel arch surrounds incorporate aerodynamic ducting to channel turbulent air efficiently, demonstrating obsessive attention to microscopic details.
| Specification | Standard GT3 | Manthey Kit |
|---|---|---|
| Downforce at 285 km/h | 355 kg | 540 kg |
| Unsprung mass reduction | – | -6 kg |
| Suspension adjustability | Fixed | Four-way adjustable |
Chassis refinement delivering uncompromising control
Beyond aerodynamic enhancements, the suspension system receives thorough optimization through four-way adjustable coilover dampers that permit trackside adjustments without specialized tools. This system enables precise tuning of compression and rebound characteristics across both low-speed and high-speed ranges, offering flexibility typically found only in professional racing environments. Such adaptability empowers drivers to dial in optimal settings for varying circuit conditions, tire compounds, and driving styles, democratizing sophisticated setup procedures previously requiring extensive mechanical expertise.
Spring rates undergo strategic recalibration, with front stiffness increasing twenty percent while rear rates decrease seven percent, creating a carefully balanced platform that manages weight transfer with surgical precision. This configuration enhances turn-in response while maintaining stability under heavy braking and aggressive throttle application. The modifications ensure consistent tire contact patch management, critical for extracting maximum grip from high-performance rubber like the optional Michelin Pilot Sport Cup 2 R compounds.

Enthusiasts can specify competition-grade brake pads for enhanced thermal capacity, while forged lightweight wheels measuring 20 inches front and 21 inches rear reduce unsprung mass by six kilograms. This weight reduction delivers tangible benefits in ride quality, suspension response, and steering precision, demonstrating how carefully considered modifications create compound performance improvements.
Exclusive personalization maintaining manufacturer support
Scheduled for availability through authorized Porsche centers from March 2026, the Manthey performance kit commands €50,750 including taxes, representing substantial investment in track-focused engineering excellence. Crucially, installation through official channels preserves full factory warranty coverage, eliminating concerns that typically accompany extensive aftermarket modifications. This arrangement offers enthusiasts peace of mind while pursuing extreme performance capabilities, a rare combination in the high-performance automotive sector.
Personalization extends beyond mechanical enhancements through carefully curated aesthetic options. Customers can specify towing hooks in red, black, or yellow finishes, while forged wheels come in silver, black, or distinctive neodymium coatings. Interior refinements include carbon fiber door sills incorporating illuminated Manthey branding, LED ground projection lighting, and exclusive badging that celebrates this collaboration between manufacturer and specialist tuner.
Key enhancement features include :
- Comprehensive aerodynamic package generating 185 kg additional downforce
- Tool-free four-way adjustable suspension system with recalibrated spring rates
- Forged lightweight wheel set reducing unsprung mass by six kilograms
- Aviation-specification brake lines with optional competition pad compounds
- Multiple personalization options for visual distinction and individual expression
The ultimate expression of naturally aspirated performance
This Manthey-enhanced GT3 represents a strategic response to enthusiasts seeking more extreme track capability from Porsche’s iconic sports car platform. While positioned below the GT3 RS in the model hierarchy, this package delivers comparable circuit performance through intelligent engineering rather than displacement increases or forced induction. The approach demonstrates how sophisticated development programs extract additional capability from existing architectures, respecting the purist philosophy that defines the GT3 lineage.
PorschePorsche wants to simulate the feel of a manual gearbox in its future EVs — a gentle revolution inspired by HyundaiThe collaboration between Porsche and Manthey Racing brings decades of combined motorsport experience to production vehicle development. Manthey’s extensive Nürburgring expertise—accumulated through countless competition victories and development programs—informs every component specification. This knowledge transfer from professional racing to road-legal applications creates vehicles that blur traditional boundaries between street and circuit machines, offering genuine dual-purpose capability without compromise in either environment.
For collectors and driving enthusiasts, this enhanced GT3 presents compelling value proposition combining exclusivity, performance, and manufacturer support. As naturally aspirated sports cars face uncertain futures amid electrification pressures, this Manthey package celebrates traditional mechanical excellence while demonstrating continued development potential within internal combustion platforms. The 7 :12 Nürburgring lap time validates this approach, proving that passionate engineering can still deliver spectacular results through fundamental physics rather than electrified assistance.
