Theon Design’s First American Model Raises the 911 Restomod Game
Britain’s Theon Design has delivered its first customer car to the United States and it’s the most advanced example of the firm’s re-imagined Porsche 911 to date.
The carbon-kevlar wide-body is finished in Midnight Blue and sits atop a 964 donor chassis which has been seam welded to increase strength and rigidity. Further weight is shed with an aerospace grade wiring harness, and to finesse the car’s balance twin air-conditioning compressors and electro-hydraulic power steering are relocated to the front and positioned as low as possible.

Five-stage adjustable Tractive dampers are fitted all round and have been calibrated especially for California’s canyon roads. A 993 RS brake package is installed, and there are 17-inch Fuchs alloy wheels wearing Michelin Pilot Sport 2 tires.
The four-liter flat-six engine punches out 410 hp at 7500 rpm, empowered by a new ceramic-coated aluminum plenum and Jenvey independent throttle bodies. For the first time, Theon has deployed a switchable engine mapping system and exhaust made possible by a drive-by-wire throttle. Town, Sport, Sport+ and Race modes can be adopted by the press of a steering wheel switch. There’s also an auto-blip system to rev-match downshifts.
Drive goes to the rear wheels via a 993 RS six-speed transmission and a Wavetrac Torsen limited-slip differential. Weighing in at just 2540 lbs fully wet, the car matches a 991 GT3 with its power-to-weight ratio.

Many of the 6000 hours of build time have gone into the cabin, where Theon Design‘s Sports Touring seats are fitted with additional bolsters and trimmed in Midnight Blue and Ibis White leather. There’s plenty of visual carbon fiber, and daily-driver features such as a phone holder ,and powerful Hertz and Audison audio system.
Theon hand-builds its cars at its base in Britain’s motorsport valley, with each one taking around 18 months to complete. Prices start at $590,000 plus the costs of a donor car, shipping, and taxes.



They made just over 60k 964s. How many more are we going to trash to build these half-baked restomods that will be dated in short order?
I’m with you there. As cool as these ‘conversions” can be, at some point they will become boring. I liked all of the 911’s from the beginning and they progressed to what I consider the BEST of them all………the 964…….PERIOD. I have admired Ruf since 1985 and before the Road and Track “Fastest Car In The World” issue in 1987. Ruf being a “manufacturer”, his builds do not take anything out of so-called Porsche production for these resto-mod creations other than customers who want to add Ruf performance parts. Ruf has been building their own, ground-up cars for 7 to 8 years now. I think it is time Singer, who are the most well known of the 964 “killers” has been around long enough and bragged about enough to maybe build their own car like Ruf has?
I see another 1 of 29 Ruf CTR’s is coming up for auction next week……….winning bid?……….who knows but probably pushing $6 MILLION like the last one a few weeks ago. Sorry Rob Dickenson, your Singers just don’t have history behind them.
$590k, Dear Lord.
For many of us, peak Porsche 911 means pre-’74, air-cooled soundtrack, light weight, and petite dimensions.
I can’t pony up 20% of what the “re-imagined” builds cost, but I haven’t tired of looking at them.
I’d rather have this than the $500k EV Bronco from ICON.
