Porsche 911 GT3 RS (992) Manthey Racing

In the battle for every millisecond, the engineers at Porsche and Manthey are among the closest partners. Thanks to their uncompromising development work, the new aerodynamics package increases downforce compared to the production car without the Manthey kit while maintaining the same drag. The spectacular result: over 1000 kg downforce at 285 km/h. For higher cornering speeds and maximized vehicle stability.

The enlarged front lip with a new wing profile, suspended on carbon reinforcement elements, generates more downforce on the front axle in conjunction with the new wheel arch gurneys and flaps. The smooth underbody connected to the front lip also contributes to a considerable increase in downforce on the front axle by improving the overall flow on the underbody. The rear window is replaced by a lightweight carbon cover, which saves 25% in weight. Mounted on it: the new carbon shark fin to increase stability when cornering. Together with the 6 additional roof fins, it also diverts the warm exhaust air from the front radiator to the outside - for cooler process air at the rear and therefore even more engine power. In conjunction with the enlarged wing end plates, the split carbon DRS wing blade increases downforce on the rear axle and enables faster acceleration out of corners. Also highly visible: the significantly wider rear diffuser. With its longer carbon fins, it transforms the optimized airflow into even more downforce without increasing drag. In addition, the carbon aerodiscs on the rear axle ensure a significant reduction in drag - and complete the close interaction of all aerodynamic components to optimize the airflow and maximize overall efficiency.

A very good mod. However, there is one significant issue. On the Nordschleife, the mod reaches speeds of over 310 km/h on the Döttinger Höhe, whereas the real car only hits 285 km/h. That is too big a difference, making the mod unrealistic. Sorry.

What an incredible machine! I am thoroughly impressed by the quality in visuals and sound and of course performance! wow just wow... As an FYI at Fuji, Weisach package was 1:48.9 and the Manthey was 1:46.8 -- that's nearly 2s all because of aero!!!???!!!??? Crazy. But here is the caveat... Top speed for the Weisach was 178 mph but the Manthey was 174.5 mph.... all that downforce! (for both tests, I did not use DRS.. I forgot lol) Edit: Just ran another test on the Weisach using DRS on the Fuji straight and no MPH gained! Does using DRS do anything??

the car is too fast on the straights and having low downforce compared to a real manthey racing car, can you please update the car to be more realistic ?

How do I get the hood to close? Everytime I load in the hood is open and the hood control only works for the driver door

Great Mod seems like, feels grippy and responsive but I cant get the dammed hood to close , Extra button E just opens the Driver side door

Just did 5 laps at the Nords in this. What a bloody brilliant car, the sounds and the driving experience is just phenomenal. Thank you so much!
