911 GT3 RS (992.1) Manthey Kit
Precisely tuned aerodynamic, chassis and high-performance brake components for the 911 GT3 RS (992) — beyond the limits of what was previously possible.
Over 1000 kg downforce at 285 km/h — with the same drag as the production car.
The Winged Monster.
The 911 GT3 RS already sets new standards with its radical aerodynamic concept and extensive lightweight construction. The Manthey Kit sharpens performance to the maximum — combined with increased controllability of the vehicle at the limit. For new ideal lines and personal best times.

Aerodynamics
The enlarged front lip with a new wing profile, wheel arch gurneys and a smooth underbody generate more downforce on the front axle. At the rear, the split carbon DRS wing blade, enlarged end plates, wider diffuser and carbon aerodiscs increase downforce without increasing drag. A lightweight carbon cover replaces the rear window, carrying the new shark fin — which, together with 6 roof fins, diverts warm radiator exhaust air for cooler process air and more engine power.
1000+ kg downforce at 285 km/h
Same drag as the production car
−25% rear window weight in carbon
Shark fin + 6 roof fins for stability and cooling

Semi-active coilover suspension
New twin-valve dampers with a newly developed control unit adjust damping automatically and in real time. In Track mode, the setup can be adjusted manually from the steering wheel.
+30% / +15% spring rates F / R
4 + 3 wheel and body acceleration sensors
2 valves per damper, independently controlled
Normal / Sport / Track mode parameter sets

Brake line set with steel sleeve
Reducing the distance between braking point and apex by crucial meters: the brake line set with steel sleeve ensures even more direct pedal feedback and the associated faster response time — optimizing response and stability.

Additional features
Illuminated carbon door sill panels with Manthey logo, LED door projectors and foiling on the carbon aerodiscs emphasize the sharpened character of the 911 GT3 RS. An optional tow strap for front and rear is designed for circuit use and must be removed before driving on public roads.
Neodymium / white / black door logos
Red / black / yellow tow strap
Foiled aerodiscs in various colors
