Porsche has just confirmed what enthusiasts have been anticipating since whispers emerged from the Nürburgring: the 911 GT3 RS equipped with the factory-backed Manthey Performance Kit has obliterated the production car lap record at the legendary German circuit, clocking an astonishing 6:44.848 around the 12.944-mile Nordschleife.
This isn’t just another incremental improvement. The Manthey-enhanced GT3 RS has shaved nearly 7 seconds off the standard car’s already-impressive time, making it the fastest road-legal production vehicle to ever tackle the Green Hell.
What Makes the Porsche 911 GT3 RS Manthey Kit So Special
The Manthey Performance Kit isn’t your typical aftermarket upgrade. Developed by Manthey Racing—the same outfit that’s dominated endurance racing at the Nürburgring for decades—this factory-approved package transforms an already extreme machine into something bordering on race-car territory.
Key components of the Manthey upgrade include:
- Adjustable front and rear carbon fiber aero elements with additional downforce-generating dive planes
- Race-derived coilover suspension with extended adjustment range
- Optimized brake cooling ducts channeling air more efficiently
- Magnesium center-lock wheels reducing unsprung weight by 10 pounds
- Recalibrated dampers specifically tuned for Nordschleife’s notorious surface changes
The kit adds approximately 170 pounds of downforce at 124 mph compared to the standard GT3 RS, while simultaneously improving brake cooling by 15%. This combination allows drivers to carry significantly more speed through the Nordschleife’s high-speed compression zones without fade.
The Record-Breaking Lap Details
Porsche factory driver Lars Kern piloted the Manthey-equipped GT3 RS during the record attempt, battling October’s unpredictable Eifel weather to secure the time. Video footage released by Porsche shows Kern extracting every ounce of performance from the naturally-aspirated 4.0-liter flat-six, which remains unchanged at 518 horsepower.
What’s particularly impressive is how the Manthey kit addresses the GT3 RS’s few remaining weaknesses. The standard car occasionally suffers from understeer mid-corner on the Nordschleife’s slower, technical sections. Manthey’s suspension recalibration and additional front downforce have effectively eliminated this characteristic.
How It Compares to Competition
The 6:44.848 time places the Manthey GT3 RS firmly ahead of high-performance rivals:
- Mercedes-AMG One: 6:35.183 (hybrid hypercar, not comparable segment)
- Porsche 911 GT3 RS (standard): 6:51.850
- Lamborghini Aventador SVJ: 6:44.970
- Mercedes-AMG GT Black Series: 6:48.047
While the AMG One technically holds the overall production car record, purists note its Formula 1-derived hybrid powertrain places it in a different category entirely. Among traditional sports cars with combustion-only powertrains, the Manthey GT3 RS now reigns supreme.
Availability and Pricing Reality Check
Here’s where things get interesting for potential buyers. The Manthey Performance Kit carries a suggested retail price of approximately $74,500—not including installation. Combined with the GT3 RS’s $241,300 base price, you’re looking at a $315,000+ proposition before dealer markups.
Porsche confirms the kit will be available through select dealers in the USA and UK starting early 2024, though production numbers remain limited. Installation requires factory training, meaning not every Porsche Center can perform the upgrade.
The kit also maintains full factory warranty coverage when installed by authorized technicians, addressing concerns from buyers worried about voiding their powertrain protection.
What This Means for Porsche’s GT Division
This record attempt signals Porsche’s continued commitment to naturally-aspirated performance even as competitors embrace forced induction and electrification. The GT3 RS remains one of the last pure analog supercars, and the Manthey kit proves there’s still untapped potential in traditional engineering.
Porsche’s GT division has hinted that future collaborations with Manthey could expand beyond track-focused packages, potentially offering street-tuned variants for customers prioritizing daily usability over lap times.
The Verdict
The Manthey-enhanced 911 GT3 RS represents the pinnacle of what’s achievable when a legendary manufacturer partners with racing specialists who’ve spent decades mastering one specific circuit. While the $74,500 price tag seems steep, it’s actually a bargain compared to purchasing an entirely different vehicle to achieve similar performance.
For Porsche enthusiasts with both the means and the skill to exploit this level of capability, the Manthey kit transforms an already exceptional sports car into a Nordschleife-dominating weapon that can still be driven home afterward. That’s the magic of modern GT cars—and why this record matters beyond the numbers.
