2023 Porsche 911 GT3 ""Manthey Racing""Chassis No. WP0AC2A96PS271065This 2023 Porsche 911 GT3 was delivered new in August 2023 to its original owner through The Collection Porsche in Coral Gables, Florida. Finished with a desirable factory specification and later upgraded with the Manthey Racing Performance Kit, this example represents one of the most focused and highest-performing variants of the 992.1 GT3 platform available.Power comes from a naturally aspirated 4.0-liter flat-six rated at 502 horsepower, paired with a GT3-specific 7-speed PDK transmission. The engine revs to 9,000 rpm and features individual throttle bodies for immediate response. Porsche quotes 060 mph in under three seconds with launch control.The 992-generation GT3 introduced a double-wishbone front suspension derived from Porsches racing program, along with extensive aerodynamic revisions including a swan-neck-mounted rear wing. Braking is handled by large cross-drilled rotors with multi-piston calipers, and the car rides on center-lock wheels.Notable Factory Options Include: Leather/Race Tex-Interior with GT Silver Stitching $4,730 Arctic Grey Paint $4,220 Carbon Fiber Roof $3,890 Front Axle Lift System $3,670 Adaptive Sport Seats Plus (18-Way) $2,640 Exterior Mirror Trim in Carbon Fiber $1,630 Bose Surround Sound System $1,600 Wheels Painted in Satin Neodyne $1,290 Exclusive Design Taillights $990 LED Headlights in Black with Porsche Dynamic Light System (PDLS) $850 Chrono Package with Preparation for Lap Trigger $550-Manthey Racing Performance Kit:This example was subsequently fitted with the Manthey Racing Performance Kit, developed by Manthey Racing in cooperation with Porsche. The package was engineered to further enhance aerodynamic efficiency, chassis response, and braking consistency on track.According to Porsche testing, a GT3 equipped with the Manthey kit recorded a 4.19-second faster lap time around the Nurburgring Nordschleife compared to the standard car.The kit includes: Enlarged rear wing with revised aero profile and Gurney flap Revised front aero elements and underbody components Carbon-fiber rear diffuser elements Lightweight forged wheels with carbon rear aero discs (reducing unsprung mass by approximately 16 lbs) Four-way adjustable coilover suspension co-developed by Manthey and Porsche Increased spring rates (approx. 10% front / 7% rear) Braided steel brake linesThe Manthey kit represented an investment of over $57,000 plus installation.---Condition & ServiceThe car has been serviced at an authorized Porsche dealership and was recently acquired by Aston Martin San Diego. It is current on service and has received new tires in preparation for sale.---Investment PerspectiveNaturally aspirated GT3 models continue to represent a shrinking segment of the modern performance market. As electrification and turbocharging become standard across the industry, high-revving engines such as the 4.0-liter in the 992.1 GT3 are increasingly viewed as the end of an era.Examples fitted with the factory-supported Manthey Racing Performance Kit remain limited relative to standard production cars and appeal to buyers seeking the most track-capable specification available without stepping into RS territory.For collectors and drivers alike, this represents a well-optioned, properly upgraded 992 GT3 with documented provenance and one of the most desirable performance packages offered for the platform.
