• The 2022 Porsche 911 GT3 with the Manthey Performance Kit is 4.19 seconds quicker around the Nürburgring than the normal GT3, according to Porsche.
  • The Porsche-backed, dealer-installed Manthey kit includes a host of aerodynamic and chassis upgrades.
  • Unfortunately, the Manthey kit is currently only available in Europe, but it's possible it will come stateside in the future.

    The Porsche 911 GT3 is a phenomenal track car. In stock form, Porsche says it lapped the famed Nürburgring Nordschleife (a.k.a. the North Loop) in just under seven minutes. Fitted with the new factory-backed Manthey Performance kit, the company says, the GT3 went around the 'Ring 4.19 seconds quicker, posting a 6:55.7 lap time. That's awesome. Less awesome is that the kit is currently only sold in Europe.

    A Porsche spokesperson told us the company is still considering making the Manthey setup available in the U.S., but a final decision is still up in the air. Meanwhile, lucky European customers who can afford a new 911 GT3 can expect to spend the equivalent of $48,000 U.S. on the dealer-installed setup. What performance upgrade does that money buy? We'll tell you.

    The Manthey Performance kit was co-developed by Porsche engineers in Weissach and Manthey's Nordschleife specialists. The kit primarily focuses on the GT3's aerodynamics and chassis components, preserving the coupe's naturally aspirated 4.0-liter flat-six. The U.S.-spec engine produces 502 horsepower at 8400 rpm and 346 pound-feet of torque at 6100 rpm. Equipped with the seven-speed dual-clutch automatic transmission, the GT3 we tested hit 60 mph in 2.7 seconds, stopped from 70 mph in 133 feet, and generated 1.11 g of cornering grip.

    Those test figures might change after the Manthey transformation, but, unfortunately, we won't know unless it comes to our shores. What we do know is that the kit increases downforce with aero alterations on the front, back, side, and even underneath of the car. The GT3's defining feature is arguably its manually adjustable carbon-fiber rear wing, which has a distinct swan-neck design. After the Manthey conversion, it grows wider and adds a Gurney flap. The other updates include a redesigned rear diffuser and "aerodiscs" on the rear wheels, all made of carbon fiber.

    Manthey-equipped models feature a specially developed suspension with four-way-adjustable coil-over shocks. The GT3's springs are also said to be 10 percent stiffer up front and 7 percent stiffer in the back. The Manthey kit even offers upgraded brake pads. Steel-braided brake lines and a towing loop, in the event an overzealous driver accidentally leaves the racetrack, are both standard. As with the normal GT3, Manthey models can be fitted with 20- or 21-inch forged wheels. A set of ultra-sticky Michelin Pilot Sport Cup 2 R tires are also optional, and they were worn by the car that set the GT3 lap record at the 'Ring.

    The Manthey Performance kit is currently available to order in Europe, and Porsche says deliveries will begin this fall.
