Gunther Werks, based in Huntington Beach, California, was founded by Peter Nam—CEO of carbon-fiber specialist Vorsteiner—with a clear mission: to reinterpret Porsche’s 993-generation 911 through the lens of the later GT3 ethos.
Each build starts with a bare steel unibody that is seam-welded for added rigidity before receiving an array of bespoke carbon-fiber components. These include a fixed carbon roof, widened front and rear fenders, revised bumpers, side skirts, and carbon front and rear lids, blending contemporary aggression with classic 911 proportions.
Unveiled in 2017, the Gunther Werks 400R introduced unique carbon bodywork and a dedicated rear wing, along with flared arches to house wider tires. Those upgrades are essential to manage the output of its Rothsport Racing–built 4.0-liter naturally aspirated flat-six, delivering 400 horsepower and 330 lb-ft of torque while spinning to 7,800 rpm. Power is routed through a Getrag six-speed manual transmission engineered specifically for the 400R.
Production was capped at just 25 examples, and one is currently listed on Bring a Trailer, showing only 2,503 miles since completion. Known as the “Bianco Rosso Commission,” this car wears a pearlescent white exterior contrasted by red accents. It rides on Fuchs-style forged three-piece wheels backed by Brembo brakes with red calipers, with numerous design cues referencing classic 911s while maintaining a thoroughly modern silhouette.
Inside, the Bianco Rosso Commission pairs exposed carbon fiber with red Alcantara and black leather. Carbon-fiber bucket seats provide excellent support and visual drama, while exposed sections of the carbon tub throughout the cabin serve as a constant reminder of the car’s engineering focus.
The Rothsport 4.0-liter engine is matched to a Getrag G50 six-speed transaxle with custom gearing, while suspension duties are handled by bespoke KW Clubsport coilovers. Although Gunther Werks has since shifted its attention to new 993-based projects, the original 400R remains the brand’s foundation—and with so few built, examples like this rarely surface on the market.
