Britain’s Theon Design has reached a major milestone – marking a decade of building modified Porsche 911s in Oxfordshire.
Situated in the UK’s ‘Motorsport Valley’ close to Silverstone, Theon Design has brought F1-style engineering to its Porsche 964-based projects. And the company’s latest restomod – pictured here – is no different.
Built for a UK client and painted in Oak Green Neo Metallic, Theon Design’s newest 911 took 18 months to develop and (re)build.
Tailored to an exact specification chosen by its owner, the Oak Green 911 demonstrates the vast array of customisation options offered by the company.
As part of its anniversary celebrations, Theon Design has just launched a new online configurator, helping potential customers to plan their perfect restomod. Or to simply dream of doing so…
Carbon fibre helps to save 300kg
The new 911 uses lightweight carbon fibre for both its exterior body panels and interior trim, helping to save 300kg versus a regular 964-generation Porsche 911.
Powering the new car is a 4.0-litre air-cooled flat-six engine, enhanced using a decade of Theon Design’s hands-on experience.
Along with a healthy 419hp and 322lb ft of torque, modern drive-by-wire technology provides instant throttle response, plus the option of multiple driving modes.
This car’s owner has chosen a five-speed ‘G50’ manual gearbox for their 911, but Theon Design also offers a close-ratio six-speed manual.
A 911 tailored to its owner
Deploying the full power of the flat-six sees the Theon Design 911 accelerate to 60mph in 4.0 seconds, aided by a kerb weight of just 1,150kg.
Porsche 993 RS-spec brake discs and calipers offer a welcome boost to stopping power. Theon Design has also fitted TracTive semi-active suspension dampers, which are combined with bespoke spring rates and an individually tuned steering setup.
All of the 911’s dynamic properties have been tailored to its owner, as has the choice of 17-inch alloy wheels. Fitted with Michelin Pilot Sport tyres, these were selected for their larger sidewalls, which offer extra compliance on the UK’s universally terrible tarmac…
Beechwood semi-aniline and nubuck leather is used throughout the interior, with shapely Recaro CS seats fitted. A new climate control system offers improved comfort, while a bespoke wiring loom shaves 25kg from the OEM Porsche item.
Retaining the Porsche spirit
Theon Design co-founder Adam Hawley said: “The air-cooled Porsche 911 has legendary integrity of design and engineering. The car’s proportions, mechanical character and unfiltered connection with the driver are fundamental to its enduring appeal.
“Our ambition has always been to elevate those qualities, while respecting the principles behind the original design. That requires experience and discipline – knowing what to evolve and, just as importantly, what to preserve.
“Ten years on, that conviction remains central to everything we do. We don’t measure progress by the changes we introduce, but by how naturally each enhancement belongs to the car. The result must feel cohesive, fully in keeping with Porsche’s engineering ethos and unmistakably true to the spirit of the original 911, as it subtly evolves into a distinctly personal character shaped by its owner.”
Theon Design is currently working on the first ‘R’ version of its ever-evolving 911 restomod. With a 500hp flat-six and a kerb weight of less than 1,000kg, performance should be even more startling – and keep the company busy for its next decade.
