Manthey Racing has unveiled a new performance kit for the Porsche 911 GT3 (992.2) that boosts aero grip, stability, and lap time—without touching the engine or voiding the factory warranty. The result is a verified Nürburgring Nordschleife lap time of 6:52.981 with Ayhancan Güven, roughly 2.8 seconds quicker than the previous 992.1 GT3 Manthey package under imperfect conditions, with total downforce now reaching up to about 540 kg at 285 km/h in circuit mode.
What’s new in the kit
Manthey focuses on high-performance aerodynamics and chassis tuning for the updated GT3, leaving the glorious 4.0-litre flat-six untouched as it revs past 9,000 rpm and sails beyond 300 km/h from the factory baseline. The aero suite adds a longer front spoiler lip, reworked underbody elements, a larger rear diffuser with bigger fins, and a larger rear wing now wearing a Gurney flap for extra stability. Manthey confirms a total downforce capability of 540 kg at 285 km/h, with baseline settings delivering roughly 355 kg—both figures engineered for higher cornering speeds and driver confidence. Four-way adjustable coilovers come standard, with approximately 10% stiffer front springs and tool-free compression and rebound changes to match the added aero load on track days. The braking hardware remains stock but gains braided stainless-steel lines for better pedal consistency and heat management during extended lapping.
Lap time and validation
Porsche and Manthey recorded a 6:52.981 lap at the Nürburgring Nordschleife over 20.8 km, cutting 2.76 seconds versus the prior-gen Manthey GT3 despite “less than ideal” conditions, driven by reigning DTM champion Ayhancan Güven on Cup 2 R tyres. Third-party reports echo the same delta and downforce envelope, noting the dramatic improvement in circuit-mode aero versus standard car settings. Manthey’s official materials and Porsche’s newsroom jointly position the kit as an OEM-backed Tequipment upgrade, available via Porsche Centres and designed specifically for track-day performance and durability.
Aero and chassis in detail
Underbody optimization extends turning vanes and smoothing elements to clean and accelerate flow, while revised canards, deeper diffuser fins, and a larger wing with reshaped endplates and Gurney flap significantly increase rear stability at speed. In circuit mode, the total downforce rises to around 540 kg at 285 km/h, a transformative jump for high-speed balance, braking zones, and fast direction changes. The four-way coilover package allows swift, tool-free adjustments of compression and rebound so drivers can tune for surface, tyre, and ambient changes between sessions. Manthey also recommends forged lightweight wheels that shave roughly 6 kg to 6 kg-plus of unsprung mass overall, further sharpening transient response and ride over kerbs.
Warranty, availability, and price guidance
The package is developed jointly by Porsche and Manthey and sold through official Porsche Centres worldwide, retaining warranty coverage and ensuring installation quality through certified technicians. U.S. availability is slated from Spring 2026 with market-specific pricing to be announced, aligning with Manthey’s historical approach to region-based MSRP and dealer install programs. As guidance, the 992.1 GT3 Manthey kit previously started near the equivalent of ₹48 lakh over the base GT3 in U.S.-aligned pricing, and expectations are for similar positioning with the 992.2 kit, still far less than stepping up to a full GT3 RS.

Who should get it
Track-day regulars who want measurable lap-time gains, higher limits, and better stability without sacrificing OEM reliability or warranty will find the Manthey kit a sweet spot beneath a full-blown GT3 RS. Owners of the 992.1 Manthey GT3 will note that the new kit’s pace and aero are a step forward; those starting with a stock 992.2 GT3 will see the most dramatic transformation per rupee on circuit days.
