The Factory Five Racing Mk3 Roadster has long been celebrated as the benchmark for high-performance component vehicles, offering an authentic driving experience modernized by contemporary engineering. This 2009-titled example is finished in a striking Sunburst Orange with silver racing stripes, presenting a bold departure from the traditional blue-and-white color schemes often seen on these platforms. Acquired by the seller in 2023, the car now shows 17,000 miles and boasts a high-specification build that prioritizes both mechanical aggression and cabin refinement. It represents a meticulously sorted machine that bridges the gap between a raw track-day weapon and a sophisticated street cruiser.
Sunburst Orange Bodywork and Eight-Stack Aesthetics
The visual character of this Factory Five Racing Mk3 Roadster is defined by its fiberglass bodywork and a series of high-end exterior accents. Polished dual roll hoops and a LeMans-style fuel cap provide classic racing cues, while the white-finished side-exit exhaust pipes feature unique copper Cobra-themed heat shields. The car rides on 17-inch Halibrand-style wheels with faux knock-off spinners, tucked under flared fenders that house functional vents and wind wings. Although a minor crack is noted on the front lip spoiler, the overall presentation is one of precision, highlighted by the velocity stacks that peer through the hood scoop when the engine is at rest.
Kirkey Racing Seats and Bespoke Carbon Details
Inside, the cabin has been significantly upgraded beyond standard kit expectations, featuring heated and ventilated Kirkey Racing aluminum seats covered in beige upholstery. The dashboard is finished in matching beige vinyl with carbon-fiber accents and houses a suite of white-dial Speedhut instrumentation, including a GPS-based speedometer. Safety is paramount, with a fire suppression system and Schroth multi-point harnesses installed for both occupants. Despite its minimalist roots, the car offers surprising comfort through integrated air conditioning and a Custom Autosound stereo system linked to Memphis speakers, all controlled behind a quick-release NRG Innovations steering wheel.
Bored and Stroked 427ci V8 Dominance
Performance is delivered by a Windsor-based aluminum block V8, bored and stroked to 427 cubic inches and fitted with FAST electronic fuel injection. This exotic setup utilizes eight individual throttle bodies with velocity stacks to produce an estimated 525 hp / 532 PS and 510 lb-ft / 691 Nm of torque. Power is funneled through a Tremec TKO 600 five-speed manual transmission and a 3.55:1 limited-slip differential. The chassis is equally advanced, utilizing adjustable Koni coilovers and multi-piston Wilwood disc brakes to manage the immense power. An Accusump oil accumulator and dual electric cooling fans ensure the high-output engine remains protected during spirited driving sessions.

Market Context and Component Rivals
The Factory Five Racing Mk3 Roadster competes in a market populated by high-end continuation cars and other component manufacturers like Superformance and Backdraft Racing. While some competitors focus on absolute period correctness, Factory Five owners typically prioritize modern chassis dynamics and customization. This specific build’s use of an aluminum-block 427 with individual throttle bodies places it at the upper echelon of the market, as these components offer a significant weight advantage over traditional iron-block engines. The addition of air conditioning and ventilated seating makes it a rare “luxury-spec” build that appeals to collectors who intend to drive their vehicles frequently rather than just displaying them.
Reliability and Long-Term Value Trends
Investing in a well-sorted Factory Five Roadster provides the benefit of a modern powertrain housed in a classic silhouette. The use of the FAST EFI system ensures that the 427ci engine starts reliably and maintains a smooth idle, a common struggle with carbureted high-performance V8s. Recent service in 2026, including air conditioning maintenance and a spark plug change, indicates a vehicle that is ready for immediate seasonal use. As the market for hand-built tributes continues to mature, examples with documented build specs and low mileage like this one remain strong assets, offering a level of visceral engagement that is disappearing from the modern sports car landscape.
