TGR StaffEvery year, the SEMA Show delivers its share of jaw-dropping builds, but few command the floor quite like a Ringbrothers creation. For 2025, the Wisconsin-based craftsmen unveiled the Ringbrothers KINGPIN, a reimagined 1969 Ford Mustang Mach 1 that blends vintage muscle with modern engineering and a heavy dose of cinematic attitude.
More than 5,500 hours went into building the Ringbrothers KINGPIN, a figure that feels right when you see the car in person. Every inch has been rethought, reshaped, and refined. Under the hood, a Wegner Motorsports 5.0-liter Coyote V8, force-fed by a Whipple supercharger, lays down north of 800 horsepower. A Bowler Transmissions Carbon Edition six-speed manual handles the grunt, while custom Ringbrothers headers and a Flowmaster Super 44 stainless exhaust provide the soundtrack.
Beneath the sheet metal, the Mustang’s soul has been recast. The team started with a Roadster Shop FAST TRACK Stage III chassis, then performed extensive surgery to merge it back into a unibody structure. The Mach 1’s body is widened two inches up front and 3.5 inches in the rear, with a wheelbase stretched forward by 1.5 inches. Michelin Pilot Sport 4S tires wrap HRE Vintage Series 517 wheels, with Fox coilovers and Brembo brakes ensuring that KINGPIN’s bite matches its bark.
Ringbrothers KINGPIN: A Sinister Aesthetic
“The Mustang Mach 1 has always been an aggressive-looking car, and the client was adamant about creating a sinister aesthetic,” said Jim Ring. “We asked ourselves, ‘What would the final boss in a John Wick film drive?’ This was the result.”
That aesthetic comes alive in a custom BASF hue dubbed Bootleg Black, contrasted with Grab-Her Green trim, a subtle twist on Ford’s original Grabber Green that nods to the Mach 1’s rebellious spirit. The car’s stance is menacing, aided by a one-off carbon-fiber rear diffuser, vented quarter panels, and a bespoke tail panel. The hood, grille surround, and front valance are also carbon fiber, as are numerous interior details. Inside, the craftsmanship continues with machined brightwork, 3D-printed accents, Dakota Digital gauges, a Vintage Air Gen IV climate system, and a custom crushed-carbon Ringbrothers “ENYO” steering wheel.
“Every piece of this car has been touched and updated,” added co-founder Mike Ring. “We sharpened the original design cues, elevated the materials, and worked with incredible partners like BASF, GENTEX, and HRE Wheels to bring it all together.”
The Ringbrothers KINGPIN isn’t a restomod, it’s a redefinition. It captures the power and attitude of a classic Mach 1 while pushing the limits of what a muscle car can be. For anyone walking the halls of SEMA, it’s a reminder that craftsmanship, when done at this level, doesn’t just preserve history, it creates it.

This car is so beautiful
I love how it is still 100% a 1969 Mach 1, but just perfected
Sexy AF
Saw it at the show, its good, but its not worth the money you know Ringbros charged
I wonder what a Ringbrothers Land Rover would look like.
As much as I want to hate these hollywood hotrods, I at least believe the Ringbrothers stuff could perform, too bad they never really get tested.
The best detail is the rear taillight treatment for the aero, chef’s kiss!
Wegner 5.0 Coyote + Whipple supercharger, Bowler six-speed manual, Fox coilovers, Brembo big brakes… this isn’t a restomod, it’s an engineering statement. Would love to see dyno sheets and lap times on this one.
Absolutely jaw-dropping work. If a muscle car could walk into a room wearing a tux, this is it. Ringbrothers took the Mach 1 and said: we’re rewriting the rulebook.
I would like to see the ringbros take their work to a brand new car, like a ringbros edition 2026 Mustang GT. Who wants a Saleen or Roush when you aren’t a racer. A stylish Mustang that could pull up on an Aston Martin and beat it for styling, fit, finish, and horsepower? Yes please.
Wish the parts and concepts from teh Ringbrothers would trickle down to us common folk.
this was the best unveil at SEMA by far.
