Manthey Racing - Storyboards

For those unaware, Manthey Racing is a German tuner based at the Nürburgring and has been racing Porsches for 25 years

Besides their racing efforts, they also develop performance kits for Porsche road cars, which are available through Porsche Tequipment

Porsche owns a 51% majority stake in Manthey-Racing, and in 2021 they became a full motorsport partner for the German brand

Mathey recently unveiled their highly-anticipated kit long-awaited kit for the 992 GT3 RS

Developed over two years, this new kit for the GT3 RS focuses on four key areas: aerodynamics, weight savings, suspension and brakes

Comprising 17 components, the Manthey Kit brings some significant upgrades when compared to the standard 911 GT3 RS

If you'll stick around, we'll show you how it differs from the standard GT3 RS; along with some exclusive shots of the global debut from the Icons Of Porsche event, recently held in Dubai

In order to improve downforce, the kit features a significantly enlarged spoiler lip up front, redesigned wheel arch Gurney flaps, and two dive planes on each side of the front bumper compared to the standard GT3 RS

Here's a closer look at the differences between the two cars upfront

Aerodynamics play a crucial role in any track-bred model and the GT3 RS is no exception. The standard variant has two roof strakes, along the edges

The function of the additional strakes is to take heat coming from the front radiator, and prevent it from entering the rear engine air intake

On the GT3 RS MR, you get six additional roof strakes, for a total of 8. They act as Vortex generators. Along with a Carbon-fiber sharkfin, it helps direct the air toward the massive wing for improved straight-line stability

This is complemented by a swan-neck mounted split-carbon fiber DRS wing, resulting in increased downforce and reduced drag

Manthey's kit also features aerodynamic hubs for the lightweight magnesium rear wheels. They work together with the rear diffuser and wing to enhance downforce

At the rear, a wider diffuser and elongated carbon fiber fins enhance downforce without increasing drag. This was a significant challenge for Manthey Racing

A closer look at the rear diffuser reveals that it is much more substantial, compared to the standard GT3 RS and has double radi

Manthey notes that a long diffuser on the standard GT3 RS extending to the underbody breaks the air flow. To address this, Manthey includes not one, but two kinks to maintain a steady air-flow

With the aerodynamic upgrades, downforce has increased by 20% over the standard GT3 RS. 2,204 lbs compared to 1,895 pounds at 177 mph

The standard GT3 RS already packs extensive CRPF (Carbon-fiber reinforced plastic) components. This top-down shot gives is a great view of the CRPF hood, roof, doors, and wing

The rear window has been replaced by a carbon fiber panel that is 25% lighter than the standard GT3 RS. The extensive use of carbon fiber means the weight savings should be substantial

Semi-active coil-over suspension along with four sensors for the wheels and three body acceleration sensors allow automatic damper tuning

This combined with spring rates increased by 30% on the front axle and 15% on the rear axle has helped improve the handling

Steel-sheathed brake lines have been added for improved pedal feel and response

The kit also includes racing brake pads specially optimized for track days

As for visual upgrades, the kit comes with a plethora of logos and decals, including door illuminated door sills

As for power upgrades, Manthey hasn't carried out any engine or transmission upgrades

Overall, the additional hardware and tweaks helps reduce dive, pitch, and roll during cornering, providing a more stable platform at high speeds

While official lap times are pending, based on extensive testing on racetracks, significant improvements are expected compared to the standard model

The 2024 Porsche 911 GT3 RS will set you back $244,995 before you start adding options

Add a few options and the Manthey kit and you are looking at a car that costs quite a bit more

We got an up-close look at the 992.1 Porsche 911 GT3 RS with Manthey Kit, which made its global debut at the 'Icons Of Porsche' event in Dubai

Here's a closer look at the eight vortex generators along with the carbon-fiber sharkfin and rear carbon fiber panel, instead of the rear windshield

The rear fin was in fact inspired by the 963 Hybrid racecar, also present at the event

Larger end plates enhance aerodynamics by preventing air from spilling off the wing tips

The carbon-fiber aero discs for the light-weight magnesium wheels, aid in improving rear-end downforce

What do you think about the 2025 911 GT3 RS MR? Please let us know in the comments below.

These spy shots by CarSpyMedia show a 2025 Porsche 911 GT3 RS MR, which is a collaboration between Porsche and Manthey Racing, aimed at enhancing the performance of the standard GT3 RS

The MR features aggressive aerodynamics, including a massive swan-neck rear wing, vortex generators, and a redesigned rear diffuser, to increase downforce and stability

Additional aero enhancements include a redesigned front splitter with dive planes, larger canards, and a huge horizontal fin replacing the rear window

Manthey is also likely to offer adjustable coil over suspension for better adjustability

Lightweight magnesium wheels with aero discs upgraded brakes and braided lines

The MR is expected to significantly improve the GT3 RS's lap times on the track

But it won't be eligible for official Nürburgring records for a production car, due to being an aftermarket kit

The Manthey Performance Kit for the 911 GT3 is expected to be more expensive than the existing kit for the standard GT3's $60,500 asking price

While the MR is a track-focused machine, it remains to be seen how many GT3 RS owners will actually take advantage of its extreme capabilities

Given that the car in the spy shots looks production-ready, the official announcement should be soon.
