Theon Design has revealed GBR008, its latest individual commission based on a Porsche 911 from the 964 generation. The car combines a full carbon-fibre body with retained steel doors, a naturally aspirated 4.0-litre flat-six, a six-speed manual gearbox and rear-wheel drive. It is not a fixed catalogue specification, but a one-off developed with its owner.
The engine produces 421 bhp and 324 lb-ft of torque. Theon uses drive-by-wire control and MoTeC electronics, with selectable modes that alter the car's response and character. The chassis adds five-way adjustable TracTive semi-active suspension and a front-axle lift system.
Wet weight is quoted at 1,146 kg. Theon says that gives GBR008 a power-to-weight ratio better than the current 992.2-generation 911 GT3. The company deliberately keeps steel doors rather than replacing every exterior panel with carbon, arguing that their weight and closing action remain part of the tactile character of an older 911.
The exterior is finished in Crayon Grey with Lizard Green accents. Smoked lights, 17-inch wheels and darker brushed trim sit against the carbon body. Inside, carbon panels are hand-trimmed in leather, Recaro RS seats carry matching detailing, and machined aluminium components are mixed with an original Becker Mexico head unit connected to a modern amplifier and speaker system.
Theon says each commission takes roughly 6,000 hours to complete. The company's output remains intentionally small: only six clients worldwide are due to take delivery of a new commission during 2026. Prices start at £430,000 before the cost of the donor car, shipping and local taxes.
GBR008 illustrates how the upper end of the restomod market has moved far beyond cosmetic restoration. The 964 remains the visual and mechanical reference point, but the body materials, engine calibration, electronics and suspension are developed with the level of attention normally associated with a new low-volume performance car.
