The heart of KINGPIN is a Wegner Motorsports 5.0-litre Coyote V8 fitted with a Whipple supercharger.
Ringbrothers and Wegner have tuned the package to deliver a headline-grabbing 800 horsepower, with power routed to the rear axle through a Bowler Transmissions Carbon Edition six-speed manual gearbox.
To complement the high-output Coyote, the car uses custom headers and a Flowmaster Super 44 Series stainless steel exhaust, a combination engineered for both performance and an aggressive, distinctive soundtrack.
Chassis, Bodywork, and Carbon Detailing
Ringbrothers performed extensive metalwork to re-sculpt the Mach 1's proportions. The body is widened by 2 inches at the front and 3.5 inches at the rear, while the wheelbase is pushed forward by 1.5 inches to refine the stance and weight distribution.
Strategic carbon-fiber components, including the bonnet, grille surround, front lip, rear diffuser, rear quarters, and tail panels, reduce mass and sharpen the design. The finish, a deep custom hue called "Bootleg Blag," reinforces the car's dark, purposeful character.
Running Gear: Modern Control for Vintage Bones
Despite its classic silhouette, KINGPIN rides on a fully modern suspension setup. Independent suspension front and rear pairs with Fox RS adjustable coilovers to deliver adjustable, predictable handling.
Stopping power is supplied by large Brembo calipers, while HRE Vintage Series 517 wheels wrapped in Michelin Pilot Sport 4S tires provide the contact patch required for the car's performance envelope.
Interior: Bespoke, Built for Purpose
The interior blends safety and refinement: a custom-built roll cage integrates with the cabin, while a crushed-carbon hoop steering wheel and Dakota Digital gauges modernize the driver interface.
Ringbrothers specified a premium climate control system and bespoke trim color dubbed 'Grab-Her Green' — a nod to Ford's Grabber Green, subtly shifted to suit the KINGPIN's villainous aesthetic.

Expert Analysis: Why KINGPIN Matters
Ringbrothers have long blurred the line between restoration and reinvention. With KINGPIN, they demonstrate that the restomod movement still has room to surprise — marrying classic proportions with supercar-grade components and modern engineering. The build showcases how targeted weight reduction, suspension geometry changes, and powertrain refinement can make a late-60s chassis perform like a modern sporting car.
For collectors and builders, KINGPIN reinforces a few enduring lessons: intelligent modernization preserves character, and careful engineering transforms show-stopping concepts into vehicles that can be enjoyed, not just displayed. Similar builds like the Ringbrothers Octavia and Hennessey's 850HP Mustang Dark Horse demonstrate this evolving approach to performance car modification.
Conclusion: A Statement of Craft and Character
The Ringbrothers KINGPIN Mustang is more than an eye-catching SEMA exhibit — it's a statement. By combining a Whipple-boosted Coyote V8, extensive metalwork, and bespoke carbon craft, Ringbrothers created a Mach 1 that honors heritage while making a compelling argument for the future of combustion-driven restomods.
If you're tracking the evolution of American muscle into the modern era, KINGPIN deserves attention: it's a technical showpiece and a cultural touchstone rolled into one dark, rapturous package. Learn more about Ringbrothers and their portfolio of high-performance builds.
