Porsche 911 GT3 Manthey kit: more downforce, tool-free setup, 6:53 at the Nürburgring

The package brings a reworked underbody, a larger rear wing with a Gurney flap, an extended front splitter, and a more developed rear diffuser. Depending on the setup, the system generates between 782 and 1,190 kg of downforce, noticeably boosting stability at high speed—making the car feel more settled through fast sections.

The suspension is fully adjustable, featuring four-mode dampers and stiffer front springs to cope with the added aero load. Owners can fine-tune compression and rebound by hand, no tools required. Optional forged wheels trim 13.2 kg of unsprung mass, while the brakes are fitted with braided lines. It’s a user-friendly setup that invites drivers to tailor the car to a circuit and their style.

The result is already on the record: the new GT3 Manthey lapped the Nürburgring Nordschleife in 6:53—2.8 seconds quicker than the previous kit—and did so in conditions that were far from ideal. For track fans, the message is clear: the updated package is even faster and more precise, with the lap time underscoring how cohesively the aero and chassis changes work together.
