992 Porsche 911 GT3 RS Manthey Performance Kit Makes 2024 Nurburgring Debut

With the Nurburgring having opened its doors for 2024 in March, one of the first prototypes to be spotted testing on the Green Hell is the 2025 (992) Porsche 911 GT3 RS with the Manthey Performance Kit.

We first covered the 992 GT3 RS sporting the Manthey Performance Kit in the fall of last year and you’ll find all the technical details and the pricing below. Meanwhile, we’ll cover what’s new for the 2024 testing season.

For starters, the carbon aero discs guiding the air around the sides of the 992 Porsche 911 GT3 RS with the Manthey Racing kit are now present on the rear wheels.

Then there’s the large fin sitting on the rear window, which reminds us of Porsche-owned Manthey’s racing heritage. In addition, we can take a better look at the rear diffuser, which easily tops the already impressive piece of the factory GT3 RS.

And you should know the one making the car dance on the Nurburgring in the spy pics below is Porsche development driver Joerg Bergmeister, as confirmed by thomas.s.photos on Instagram.

Since the Manthey Racing Kit for the 992 Porsche 911 GT3 RS is street legal, you can expect the machine to set the record for the fastest naturally aspirated production car on the Nurburgring, taking this from the “standard” GT3 RS.

The Manthey Racing kit for the 992 GT3 RS will make its debut in the coming months—keep in mind Porsche is also releasing the updated 992.2 911 this year (2025MY), even though the 992.2 GT3 RS should arrive in 2025 (2026MY).

992 Porsche 911 GT3 RS with Manthey Performance Kit in detail

Have you ever wondered what a day in the life of the Nurburgring’s dedicated notary looks like? Well, as stated above, if it includes the names Porsche and Manthey Racing, the notary will probably have to certify a new world record. At least that’s what we’re expecting for the upcoming 992 Porsche 911 GT3 RS Manthey Performance kit, which was spotted testing at the Nurburgring this week.

For many decades now, many Porsches have emerged as the fastest cars in their racing classes, albeit while often facing adversaries with meatier outputs. Of course, this has translated to Porsche road cars, but with the 992 911 range now holding around 25 models, which one to choose if you’re looking to be the quickest on the track?

That would be the 911 GT3 RS, which currently holds the record for the fastest naturally aspirated production car on the Nurburgring thanks to a lap time of 6:49.328 seconds.

Well, German racing team and road car performance specialist Manthey Racing—of which Porsche owns 51 percent—is currently working to beat that lap time.

Rumored for quite a while now, the 992 Porsche 911 GT3 RS Manthey Performance kit, which should debut by the end of 2023, is now lapping the Nurburgring at a pace so extreme the spy photographer posted right outside the Green Hell needed to work just as hard as the car’s driver to keep up—lens tip to CarSpyMedia for the video below.

Based on what the Porsche 911 GT3 Manthey Performance kit has to offer, the 992 GT3 RS Manthey Performance will leave the power untouched (518hp/525 PS from a free-breathing 4.0L flat-six) while upgrading the aero, suspension, brakes, and—as an option—the wheels.

Maybe you think lap times are silly and just want to enjoy the ride. However, the whole idea with the Manthey kits is to bring the average enthusiastic driver closer to the point where they can fully take advantage of what these Porsches can offer on a circuit. Thus, the company estimates that while factory driver Kevin Estre shaved 4s off the “standard” GT3’s lap time with the Manthey Performance kit, the difference could climb to 10-15s for track day aficionados who don’t do this for a living.

What do the aero discs do for downforce?

So, making a list based on the GT3 Manthey Performance, the 992 GT3 RS Manthey Performance will offer 4-way adjustable coilovers, brake pads, and brake lines, as well as aerodynamic elements. The latter involve a front lip, canards, underbody air guide elements, a larger rear wing and rear diffuser, plus aero discs that guide the air around the sides of the car so the rear wing can generate downforce more efficiently—hey, don’t tell anybody about the Pink Pig Porsche tractor that has not one, but two wings!

In other words, rear aero discs, which fit both the Porsche and Manthey wheels, allow the angle of the rear wing to be reduced, so more downforce can be generated with less drag. Oh, and all of the pieces above are also offered on the ex-gen 991.2 Porsche 911 GT3 RS Manthey Performance.

Of course, there will be some differences between the Manthey Racing kits for the GT3 and GT3 RS. And the first example that comes to mind is that while the factory GT3 RS makes three times as much downforce as the stock GT3, the former comes with a DRS (drag reduction system) that allows the driver to flatten the rear wing and boost straight-line speed.

992 Porsche 911 GT3 RS Manthey Performance price

Once again based on the GT3 package, the 992 Porsche 911 GT3 RS Manthey Performance kit should cost at least $57,300 (including installation) and also be offered in the US. And those optional lightweight forged wheels should come at an extra $15,500. Note that, regardless of the wheel choice, Manthey’s wheel alignment is a key component of the pack.

To put that into perspective, I’ll mention the $241,300 MSRP of the 992 GT3 RS—nobody and I mean nobody buys these without options and that is if you can get an allocation.

Now, that some 30 Porsche dealers across the world include Manthey Performance kits in their Tequipment offer, so you can have the upgrade done straight at the dealership.

In the meantime, this third-party 992 Porsche 911 GT3 Cup Car conversion kit for the road car should keep you Porschephiles busy.
