The Porsche 911 GT3 has long been a favourite among enthusiasts who push their cars to the limit on track days, and the new Manthey Kit takes its performance to a whole new level. Designed specifically for those with a passion for high-speed circuit driving, the package builds on the Weissach Package with upgraded aerodynamics, suspension, and braking components.
The result is a car capable of lapping the Nürburgring Nordschleife in 6:52.981 minutes—nearly three seconds quicker than its predecessor fitted with the same kit.
Developed in close collaboration between Porsche’s Weissach Development Centre and Manthey engineers in Meuspath, the Manthey Kit is available through Porsche Centres worldwide. Its focus is on maximising downforce, improving cornering speeds, and ensuring the car can handle the intense demands of track use.
The suspension has been specially adapted for circuit driving, with four-way adjustable coilovers allowing rebound and compression to be fine-tuned without tools. Spring rates on the front axle have been increased by 10 per cent over the previous generation, enhancing stability and mechanical grip, particularly over kerbs.
