The Porsche 911 GT3 Manthey Kit brings a sharper edge to track driving and raises performance with focused upgrades. This package enhances downforce, stability and confidence for committed circuit enthusiasts.
Sharper aerodynamics for higher stability
The Manthey Kit pushes the GT3’s aero design further. A wider rear wing with a Gurney flap teams with longer diffuser fins to strengthen stability. Revised front elements guide airflow and increase grip at high speed.
Downforce increases without added drag
Extended underbody vanes and a smoother floor raise overall efficiency. In road mode, the kit delivers 355 kg of downforce at 285 km/h. In circuit mode, output rises to 540 kg, helping the GT3 stay planted through fast corners.
Chassis tuned for precision on track
A four-way adjustable coilover suspension was developed to support the stronger aero loads. Rebound and compression can be altered without tools, allowing quick setup changes during track days.
Brake and wheel upgrades for durability
Braided steel brake lines improve consistency, while optional PCCB race pads deliver stronger bite. Lightweight forged wheels cut unsprung mass by six kilograms to boost response over kerbs.
Performance and power in focus
The naturally aspirated flat-six remains central to the GT3’s character. Its sharp throttle response and high-rev power delivery combine with the new aero and chassis setup to create faster cornering and improved stability.
Exterior enhancements for added individuality
Optional carbon aerodiscs, illuminated sill trims and Manthey badging add visual identity. Tow straps and coloured accessories support circuit use while keeping the look purposeful.
Proven gains on the Nürburgring
The GT3 Manthey Kit cut its Nordschleife time to 6:52.981 minutes. Despite damp patches, the lap was nearly three seconds faster than the previous generation using similar tyres.
Summary
The Porsche 911 GT3 Manthey Kit elevates aerodynamic stability, chassis feedback and braking confidence. Its upgrades help skilled drivers unlock more pace while keeping the GT3’s purist character intact.
