The Porsche 911 GT3 S/C is the sportiest and lightest open-top 911 ever built, and it makes no apologies for what it is. A 4.0-liter, naturally aspirated flat-six revving to 9,000 rpm, a six-speed manual transmission, a curb weight of 3,322 pounds, and 502 horsepower; all of it wrapped in a cabriolet body that puts the sky directly overhead. This is not a GT3 compromise. The Porsche 911 GT3 S/C is the GT3 of cabriolets, and Bulletproof Automotive carries the full lineup.
The 0-60 run lands at 3.7 seconds. Top track speed is 194 mph. These numbers belong to a car that also drops its roof and lets that naturally aspirated engine note fill the air without any filtering. That combination is exactly what makes the Porsche 911 GT3 S/C its own argument.
The 4.0-liter, six-cylinder naturally aspirated boxer engine at the heart of the Porsche 911 GT3 S/C produces 502 hp and 331 lb-ft of torque. The redline sits at 9,000 rpm; you know it because the engine tells you. The character at high rpm is the whole point of a naturally aspirated unit at this displacement, and Porsche built this one without a turbocharger specifically to preserve that experience.
The transmission is a six-speed GT Sport unit with shortened gear ratios and a shorter gear lever for a more direct shift feel. Porsche lists this manual gearbox as roughly 37 pounds lighter than the seven-speed PDK offered in the standard 911 GT3. That weight difference is intentional; the GT Sport manual fits the Porsche 911 GT3 S/C’s character better than a paddle-shift setup could.
The sport exhaust system that runs with this engine is standard, and with the roof down, you get the full note of the high-revving flat-six without insulation. That openness is the Porsche 911 GT3 S/C’s loudest feature.
The Porsche 911 GT3 S/C uses carbon-fiber reinforced plastic (CFRP) across multiple structural and chassis components. The anti-roll bar, the connecting links of the rear axle, and the rear underbody panel are all CFRP. The standard wheel fitment runs 20-inch fronts and 21-inch rears in lightweight forged magnesium, which Porsche developed specifically for the GT3 lineup. Combined, these choices keep the car at 3,322 pounds; competitive for an open-top sports car at this performance level.
Braking is handled by the Porsche Ceramic Composite Brake (PCCB) system, fitted as standard on the Porsche 911 GT3 S/C. PCCB delivers higher braking performance than conventional iron rotors, with consistent brake pressure and strong resistance to brake fade. For a car that spends time at sustained high speeds, that fade stability is the practical point; not just the ceramic specification.
An optional carbon fiber exterior package is available, adding carbon-weave airblades on the front fascia, exterior mirror uppers, window triangle trims, and a gurney flap. This package extends the CFRP theme to the exterior for owners who want that detail visible.
Optional folding lightweight bucket seats in CFRP with carbon-weave finish and electric height adjustment are expected to be available from November 2026. These provide optimal lateral support for the driver and passenger without the weight penalty of conventional sport seating.
Porsche offers an optional Street Style package for the 911 GT3 S/C, developed by the Style Porsche design studio in collaboration with Porsche Exclusive Manufaktur. The package is expected to be available from September 2026.
The Street Style package centers on a specific design language built around contrasting color accents and material choices. Seat centers use a four-color braided leather across the 18-way adaptive sport seats. The door opening loops, seat release loops, and seat belts are in Guards Red. The headrests carry the Porsche crest outline embroidered in Guards Red.
Inside, the dashboard, cowl frame, headliner, interior mirror console, and sun visors are finished in perforated Slate Grey Race-Tex; the same suede-like material used in Porsche motorsport programs. The gear lever gets an open-pore laminated wooden ball in darkened walnut with a shift pattern in Pyro Red. The GT3 S/C model designation badge on the gear area also runs in Pyro Red.
On the exterior, the Street Style package adds decorative graphics on the fenders and PORSCHE lettering along the sides in Pyro Red. The 20/21-inch GT3 lightweight forged magnesium wheels in the package finish are Slate Grey Neo with Pyro Red accent stripes painted into the wheel barrel. Brake calipers are finished in Victory Gold with PORSCHE lettering in black.
An optional rear box, tailored to the Porsche 911 GT3 S/C’s dimensions, offers approximately 80 liters of storage. It is available in Slate Grey leather with Guards Red accents when ordered with the Street Style package, or in black leather with individually selectable accent colors when ordered separately.
Owners of the Porsche 911 GT3 S/C also receive access to an exclusively made Porsche Design Chronograph 911 GT3 S/C, hand-crafted at the Porsche watch manufactory in Grenchen, Switzerland.
