Porsche’s renowned tuning division, Manthey-Racing, has unveiled an upgraded kit for the already formidable 992-generation Porsche 911 GT3 RS. This track-ready marvel is now faster and more aerodynamic than ever, but the enhancements come at the cost of one key feature: rearward visibility.
Manthey-Racing: Porsche’s Performance Vanguard
As Porsche’s in-house tuning specialist, Manthey-Racing holds a reputation akin to AMG for Mercedes-Benz or BMW M. While Manthey’s modifications are applied post-production, the enhancements are fully backed by Porsche’s warranty, making it the ultimate upgrade for 911 purists and racing enthusiasts.
With the new Manthey Kit, the GT3 RS pushes the boundaries of what a road-legal sports car can achieve. Though the flat-six engine remains untouched, the focus on aerodynamics and chassis performance elevates the driving experience to unprecedented levels.
Aerodynamics Reimagined: Shark Fins and Carbon Panels
Central to Manthey’s upgrades is a bold aerodynamic package inspired by Porsche’s racing pedigree. A carbon-fiber rear window panel—25% lighter than the original glass—is coupled with a striking “shark fin,” a nod to Porsche’s Le Mans-winning 963 prototype. This design improves high-speed stability and contributes to increased downforce, transforming the GT3 RS into a track beast.
The kit also introduces a reinforced front splitter, Gurney flaps on the wheel arches, dive planes, and a redesigned rear wing. Together, these elements deliver a jaw-dropping 1000kg of downforce at 285km/h—16% more than the standard GT3 RS. Rear wheel “aerodiscs” further optimize airflow, reducing drag while maximizing grip.
Suspension Upgrades to Match the Downforce
To handle the extreme aerodynamic load, Manthey has re-engineered the suspension with stiffer springs—30% in the front and 15% in the rear—and new dampers featuring separate rebound and compression valves. Drivers can customize their suspension setup via three modes: Normal, Sport, and Track, ensuring the car remains composed under any driving conditions.
Brake Enhancements for the Demands of the Track
Stopping power is just as critical as speed, and Manthey delivers with upgraded brakes. The kit includes steel-sheathed brake lines and race-grade brake pads, offering improved durability and heat resistance for intense track use. However, the brake pads require the optional Porsche Ceramic Composite Brake (PCCB) package to be installed on the base car.
Track-Focused Interior and Styling Touches
Inside, the Manthey-tuned GT3 RS retains its motorsport DNA with carbon-fiber-backed bucket seats, a roll cage, and Alcantara trim. Manthey adds subtle details like illuminated carbon-fiber door sills, branded puddle lights, and an optional towing eye. For those seeking the ultimate in track-ready aesthetics, the Weissach Package offers magnesium wheels and additional carbon-fiber components, reducing weight while adding an aggressive edge.
Performance on the Nürburgring: Breaking Records Again?
While Porsche has yet to announce a Nürburgring lap time for the Manthey-equipped GT3 RS, expectations are high. The standard GT3 RS set a blistering lap of 6:44.848 in 2022, just 1.2 seconds behind the previous production car record holder, the Mercedes-AMG GT Black Series. Manthey’s modifications could potentially shave seconds off this time, further cementing Porsche’s dominance on the legendary circuit.
Legacy of Excellence
Manthey-Racing is no stranger to the Nürburgring, having claimed victory in seven editions of the 24-hour endurance race. Their expertise extends globally, with recent triumphs at events like the Bathurst 12 Hour. This wealth of experience translates directly into the development of performance upgrades like the new Manthey Kit, ensuring Porsche enthusiasts get the best of motorsport engineering.
A Faster, Sharper, and More Extreme GT3 RS
With its enhanced aerodynamics, upgraded suspension, and race-proven braking system, the Manthey-tuned Porsche 911 GT3 RS is a testament to the relentless pursuit of performance. While rear visibility may take a backseat, the driving experience is anything but compromised. This is a car built to dominate on the track and turn heads on the road, solidifying its place as one of the most exhilarating 911 variants ever created.
