Porsche Cars North America’s headquarters are in Atlanta, Georgia, and nearby in Braselton, Georgia, is the Michelin Raceway Road Atlanta, one of the country’s most iconic racing venues and the home of the annual Petit Le Mans endurance race. There, Porsche brought three 911s to the circuit with hopes of domination, and all of them were equipped with Performance Kits from Manthey Racing, which are made available for Porsche’s top-brass GT cars to take their track performance to an unprecedented level.
Manthey Performance Kits often tweak the aerodynamics, chassis, and suspension of already highly impressive performance vehicles, and they proved their abilities at Road Atlanta on the 2019 Porsche 911 GT2 RS, the 2025 Porsche 911 GT3 RS, and the new 2026 Porsche 911 GT3. Porsche brand ambassador and former factory driver Joerg Bergmeister was behind the wheel of all three, and the success on the track included a new production car lap record for the track.
That was achieved with the 2019 Porsche 911 GT2 RS, which, even after almost a decade, continues to be a global benchmark for track-focused performance. With a twin-turbocharged 3.8-liter boxer six-cylinder engine, the 911 GT2 RS with the Manthey Kit beat the previous production car lap record by 0.2 seconds. The lap time, achieved with Michelin Pilot Sport Cup 2 R N0 tires, was 1:22.649. Combining the GT2 RS’s immense power with increased downforce, the performance is nothing short of formidable.

Meanwhile, the 2025 Porsche 911 GT3 RS, which boasts up to 2,200 pounds of downforce with the optional Manthey Performance Kit, achieved a lap time of 1:23.932, becoming the fastest naturally-aspirated production car to lap Road Atlanta, and only a second short of the record-breaking 911 GT2 RS. About it, Bergmeister says, "The downforce of this car is simply incredible.“
The 2026 911 GT3 achieved an impressive time at Road Atlanta, as well, lapping the track with the available Manthey Kit in just 1:24.639. The time is 1.8 seconds faster than the 992.1 911 GT3 from 2022, proving itself to be an improvement on an already respectable track-focused car. Each of the three 911s with Manthey Kits proved their incredible performance engineering at Road Atlanta, reinforcing Porsche's track domination near its American home turf.
