Manthey’s Return to the GT3 Results in a Sharper Edge for Porsche’s Track Star

Porsche’s 911 GT3 has long been known for straddling the line between everyday usability and track-ready performance. Now, with the latest Manthey kit, designed specifically for the new 992.2 model, that delicate balance has moved substantially in favor of the track.

The core of these upgrades is downforce, or the creation of a large amount of aerodynamic force to keep the car grounded in any given corner. They managed to pull in 782 pounds of downforce in the mixed driving arrangement, but when you switch to the complete track configuration, it increases all the way up to 1,190 pounds – a level of grip you’d expect to see on a dedicated race car. Now, I see what you’re thinking: all that more grip would have to come at the expense of increased drag, which would only serve to slow the automobile down. However, the engineers working on this project did not follow that approach. They actually modified the bodywork to inject that more grip without adding any unnecessary drag.

They lapped the Nürburgring Nordschleife in 6:52.981 minutes, which is 2.76 seconds faster than the previous 992.1 GT3 equipped with the Manthey equipment. Even when the weather wasn’t ideal, this gadget managed to post times that hinted at all kinds of latent potential on a bright day.


So, what is driving this change? For starters, the aerodynamics are being driven by extensive front-end changes. The bumper has been redesigned to increase airflow to the brakes, and it also features a pair of carbon fiber canards to assist cut through the wind. The splitter has been extended by half an inch to help direct airflow exactly beneath the nose. On the sides, the skirts are now closer to the body, smoothing up the airflow as it sweeps around the sides. When you combine all of this with the original characteristics, you have a car that wants to hug the road, giving drivers the confidence to stop somewhat later and turn in harder.



The rear is where you’ll discover even bolder moves. A carbon fibre swan-neck wing has been expanded and widened for the 992.2, and it even has a Gurney flap to improve efficiency. Below it, the carbon diffuser has been pushed out further, and the fins have been expanded to extract even more downforce from the exhaust wake. And at the wheels, carbon fiber aerodiscs grab hold of the air, reducing turbulence that would otherwise slow the car down. Even under the car, the turning vanes have been extended all the way out to 59 inches, nearly double the original length, needing a bespoke cover over the baggage area to preserve smooth airflow. Despite all of these alterations, the whole unit still bolts on in the dark, and if the work is done by a licensed technician, the manufacturing guarantee remains intact. It’s worth noticing that the cargo area has remained unaffected, which is just as well given that the flat cover clearly indicates what the priorities are here.


Suspension tuning takes it up a notch. Four-way adjustable coilovers means you can tweak compression and rebound without tools, perfect for quick sessions. Front springs are 10% stiffer than the previous kit to counter the aero load while keeping the ride compliant on the street. Braided stainless steel lines feed the brakes for better pedal feel without swapping out the rotors or calipers. Optional forged wheels, 20 inches up front and 21 in back, shave 13.2 pounds of unsprung weight overall so the tires can follow the road better. Smaller details like illuminated door sills and tow straps round out the package, adding a bit of purpose-built flair.


Lap times only tell part of the story, as past tests of the previous Manthey GT3 at Virginia International Raceway’s Lightning Lap shaved 0.8 seconds off the stock car’s time, with most of the gains coming from the corners despite a slight hit to top end from the aero. Expect similar here, amplified. The 992.2 starts from a stronger base, after all, with its own chassis tweaks and the option for a manual gearbox that many purists love. Manthey’s involvement, backed by Porsche’s stake in the company, means the kit is tailored to the GT3’s character without going full race car.

Availability starts in spring 2026 through U.S. Porsche Centers, but pricing is still under wraps for now. When the previous version debuted, it cost $57,300 + $15,500 for the lightweight wheels. For those looking for that extra tenth of a second or just a GT3 that feels alive in every corner, this kit delivers without fail.
