A 2025 Porsche 911 GT3 RS equipped with the Weissach Package and a Manthey Racing performance kit has been listed for sale in Utah, offering one of the most track-focused road cars on the market with just 3,600 miles on the odometer. The car was originally delivered to the Porsche Track Experience in Leeds, Alabama, and served as a manufacturer marketing and track-use vehicle before being acquired by the selling dealer in 2026.
The Weissach Package reduced weight through a carbon-composite roof panel, front lid, anti-roll bars, and interior trim. The subsequent Manthey Racing kit added revised aero elements, semi-active coilovers, braided brake lines, and rear-wheel aerodiscs. The result is a machine that blends factory engineering with race-derived upgrades.
Finished in Black over matching leather and Race-Tex, the car is powered by a 4.0-litre flat-six producing 518 horsepower and 342 lb-ft of torque. Power is sent to the rear wheels through a seven-speed PDK dual-clutch transaxle and an electronically locking differential with Porsche Torque Vectoring Plus. The engine features direct fuel injection, VarioCam variable valve timing, dry-sump lubrication, and individual throttle bodies. A Porsche-recommended 10,000-mile service was carried out in April 2026, and the car received Porsche Approved certification the following August.
The exterior is distinguished by a carbon-fibre-reinforced plastic front trunk lid, roof panel, and rear swan-neck-hinged wing with drag-reduction functionality. Manthey Racing aero components include a revised front splitter and flaps, wheel-arch gurneys, roof blades, a rear diffuser, and underbody air guides, along with carbon-fibre rear wing blades, end plates, and a shark fin with a rear-window insert. LED-Matrix headlights with the Porsche Dynamic Light System Plus, a rear fog light, and dual centre-exit exhaust outlets complete the look. Paint-protection film is said to cover the front end.
The car rides on centre-locking 20-inch front and 21-inch rear magnesium wheels with carbon-fibre rear aerodiscs, wrapped in 275/35 and 335/30 Pirelli P Zero Corsa tyres. Braking is handled by Porsche Ceramic Composite Brakes with ventilated and cross-drilled rotors. Rear-axle steering, a front-axle lift system, and the Weissach Package's carbon-fibre anti-roll bars and coupling rods are also fitted. The Manthey Racing package added adjustable semi-active coilovers and braided stainless-steel brake lines.
Inside, heated 18-way power-adjustable adaptive sport seats are upholstered in black leather and Race-Tex with silver stitching and Weissach RS headrest embroidery. Carbon-fibre trim accents the cabin, which also features dual-zone automatic climate control, illuminated Manthey carbon-fibre door-sill plates, Silver Grey seat belts, black door-pull straps, aluminium pedals, ambient lighting, Porsche Communication Management, and cruise control. The suede-wrapped steering wheel has silver stitching, a yellow centring stripe, and a drive-mode selector dial. A central tachometer with a 9,000-rpm redline, a digital speed readout, dual configurable TFT screens, and a dashboard chronograph complete the driver's interface.
The window sticker lists a total price of $304,655 and initial delivery to the Porsche Track Experience in Leeds, Alabama. The car is offered with a clean Carfax report, a CPO certification record, and the manufacturer's Certificate of Origin. It has never been sold to a private-party owner and does not have a title; the selling dealer will assist the buyer with registration and titling.
