Reimagining Perfection: Theon Design’s Masterful Porsche 911 Restomod

In the world of automotive restomods, few names command as much respect and admiration as Theon Design. Based in Oxfordshire, England, this boutique engineering firm has carved out a niche by breathing new life into classic Porsche 911s, particularly the 964-generation models. Their latest creation—a 407-horsepower air-cooled stunner—is not just a car; it’s a symphony of design, engineering, and passion that pays homage to Porsche’s legacy while pushing the boundaries of modern performance.

🛠️ Engineering Excellence Meets Classic Soul

At the heart of Theon Design’s philosophy is a meticulous approach to craftsmanship. Each build begins with a donor Porsche 964, which is stripped down to bare metal and 3D-scanned for precision. The chassis undergoes RS-style seam welding to enhance rigidity, setting the stage for a transformation that’s as much about performance as it is about aesthetics.

The latest model, dubbed the “GBR Coupe,” features a 3.8-liter flat-six engine derived from Porsche’s original 3.6-liter block. This powerplant delivers a staggering 407 horsepower at 7,600 rpm and 293 lb-ft of torque, a significant leap from the original 964’s 247 hp. Theon achieves this through bespoke throttle bodies, a performance ignition system, and a valved exhaust that can switch between a throaty roar and a subdued hum—perfect for both spirited drives and quiet neighborhood cruising.

🕹️ Driver-Centric Dynamics

Theon Design doesn’t just build cars; they craft driving experiences. The GBR Coupe features a five-speed manual transaxle that channels power to the rear wheels with a mechanical, reassuring shift feel. Pedals are repositioned for optimal heel-and-toe action, and the accelerator mimics the latest 911 Carrera T for a modern touch.

Suspension is another area where Theon’s expertise shines. The car is equipped with TracTive semi-active shock absorbers offering five settings, allowing drivers to fine-tune body control and comfort. Springs are slightly softened to handle rough British roads, and braking is handled by Porsche 993 Carrera RS components, ensuring confidence-inspiring stopping power.

🧬 Lightweight Innovation

Weight reduction is a cornerstone of performance, and Theon Design takes it seriously. Their most powerful build to date, commissioned for a U.S. customer, weighs just 2,540 lbs thanks to F1-grade carbon kevlar bodywork and an aerospace-grade wiring loom that shaves off 30 kg. Even the rear seats are removed—not just for weight savings, but to create space for a bespoke luggage set.

This model also features a 4.0-liter flat-six engine producing 421 bhp and 330 lb-ft of torque, giving it a power-to-weight ratio that surpasses even the Porsche 911 992.1 GT3 RS. The engine sits low in the bay for better weight distribution, and components like the air conditioning and power steering pump are relocated to the frunk to maintain a 46:54 balance.

🎨 Aesthetic Brilliance

Visually, Theon’s 911s are achingly beautiful. The GBR Coupe sports a deep green finish that complements its retro-modern styling. Hand-beaten steel and carbon fiber panels blend seamlessly, preserving the classic silhouette while adding a contemporary edge. Inside, the cabin is a blend of luxury and nostalgia, with materials and finishes that evoke the spirit of vintage Porsche while offering modern comfort.

🌍 A Global Obsession

Theon Design’s creations are not just confined to the UK. Their builds have found homes across the globe—from Chile to the United States—each tailored to the owner’s preferences. Whether it’s a track-focused beast or a grand tourer for cross-country road trips, Theon delivers a cohesive package that’s as usable as it is thrilling.

🧠 The Minds Behind the Magic

Founded in 2016 by Adam Hawley, a former OEM designer with experience at BMW, Lotus, and Airbus, Theon Design is a fusion of technical prowess and artistic vision. Hawley’s CAD expertise and obsessive attention to detail are evident in every build. Alongside co-founder Lucinda Argy, Theon has grown into a brand that rivals even the likes of Singer in the restomod arena.

🚀 Final Thoughts

Theon Design’s Porsche 911 restomods are more than just cars—they’re rolling works of art that celebrate the past while embracing the future. With each build, Theon redefines what it means to drive a classic, offering a visceral, engaging experience that few modern cars can match. For enthusiasts who crave authenticity with a dash of innovation, Theon Design is the ultimate destination.
