Manthey Unveils New Kit For 992.2 Porsche 911 GT3

Manthey dials in the Porsche 911 GT3 yet again.

Porsche’s lineup of cars with the hallowed “GT” moniker are some of the most serious Porsche performance machines to ever roll off the manufacturers’ assembly lines. Previously only reserved for track-focused, serious versions of the 911, the GT lineup has expanded to include the 718 Cayman, and the Cayenne and Taycan Turbo GT models. However, one racing specialist division of Porsche does even more to make Porsche’s GT models racing-ready performance powerhouses, and that is Manthey Racing, a creator of kits that give cars like the Porsche 911 GT3 even more circuit-focused performance prowess.

Being an undeniable staple at track days, the Porsche 911 GT3 is the subject of a new Manthey Kit, which is not only another kit dedicated to enhancing the track performance of the GT3, but one that has specifically proven its ability to improve the lap time of the race-ready Porsche on the Nürburgring, not only compared to the standard 992.2 Porsche 911 GT3, but also compared to the previous Manthey Performance kit.

The kit is available to be installed for Porsche 911 GT3s at Manthey-certified Porsche Centers throughout the country, and it doesn’t compromise any existing factory warranty on the vehicle. It significantly enhances the aerodynamic performance of the car, with components that efficiently increase downforce to as much as 1,190 pounds. In addition, an adjustable coilover suspension allows owners to change the rebound and compression without tools and enjoy greater spring rates, allowing even better track versatility than the car typically offers.

LIghtweight wheels with 20 and 21 inches of diameter are available with the kit, along with braided steel brake lines. With the kit equipped, the car managed to improve its Nurburgring lap time by 2.76 seconds compared to the 992.1-generation 911 GT3 with the Manthey Performance Kit. Specifically, that time was 6:52.981, an absolutely blistering lap time for the 12.9-mile circuit with notoriously challenging bends and dramatic elevation changes. The new Manthey Performance Kit for the 992.2-generation Porsche 911 GT3 will be availalbe starting in the spring of 2026, with specific pricing details yet to be announced.
