All I Want For Christmas Is A 2026 Porsche 911 GT3 With A Manthey Kit
Key Points
- Manthey’s newest upgrade package pushes the 992.2 Porsche 911 GT3 to a Nürburgring lap time nearly three seconds quicker than the previous Manthey-equipped model.
- Aerodynamic and chassis revisions—new splitters, canards, a swan-neck wing, longer underbody vanes, and four-way adjustable coilovers—lift downforce to as much as 1,190 pounds without altering the GT3’s 4.0-liter flat-six.
- The kit will reach certified Porsche Centers in the U.S. beginning spring 2026, with pricing to be announced closer to its arrival.
Porsche’s relationship with Manthey Racing has just produced another weekend weapon—the new Manthey package for the 992.2-generation GT3 focuses entirely on aerodynamics and chassis tuning, which chops a chunk of time off the car's Nürburgring lap time.
2026 Porsche 911 GT3 Manthey Kit: All The Details
Scheduled for U.S. availability in 2026, the kit brings aerodynamic, suspension, and brake upgrades that collectively trim 2.76 seconds from the outgoing Manthey-equipped GT3’s Nürburgring lap time. 2.76 seconds may not sound like a lot, but on track, 2.76 seconds might as well be an eternity—if you're 2.76 seconds slower than your teammate, well, you're getting fired, or you're just a pay driver helping to keep the lights on.
Now, the better question is, can the average PCA member actually wheel the 911 GT3 well enough to actually extract that 2.76 seconds?
The most noticeable changes sit on the surface. Manthey reworked the GT3’s front bumper with additional venting, new canards, and a revised splitter, while the side profile now carries reshaped skirts designed to better stabilize airflow.
Like other Manthey kits, the rear wheels wear aero discs, and the tail end adopts a larger carbon-fiber diffuser and a swan-neck wing, aping the GT3-spec 911 GT3 R race car. Depending on how the car is configured, downforce can range from 782 pounds to as much as 1,190 pounds.
Out of sight, Manthey replaced the GT3’s stock underbody turning vanes with substantially longer ones, helping the car generate more consistent stability at higher speeds.
The suspension moves to a set of four-way adjustable coilovers tuned specifically for the updated aero load, with front spring rates about ten percent stiffer than the previous Manthey setup. Stainless steel brake lines are standard with the package, while the Manthey-spec forged wheels—20 inches up front and 21 out back—are available as an option.
As always, Manthey adds a handful of superfluous cosmetic touches—optional door sills with illuminated branding.
The naturally aspirated 4.0-liter flat-six carries over unchanged, which shows just how much faster any car can go with aero management and chassis refinement alone. DTM champion Ayhancan Güven posted a 6:52.981 in the Manthey-equipped GT3 at the Nürburgring. Porsche noted the time was clocked in “less than ideal conditions,” meaning there's probably a bit more capability baked into the hardware.
Pricing will come later, but it won't be cheap—the last Manthey GT3 kit added nearly $60,000 to the cost of the base car.

It's a trick question. Of course the average buyer cant get any real world advantage. But any 911 is a want, not a need. So if you want one, are spending your own money, and rich enough to not care how much it costs, the by all means buy it! :)
