There are restomods… and then there’s whatever dark alchemy Ringbrothers have just conjured up in a quiet Wisconsin workshop. It’s called KINGPIN, and it’s not just another SEMA show car. It’s a 1969 Mustang Mach 1 reimagined with the kind of obsessive precision that borders on madness — 5,500 hours’ worth of cutting, shaping, and metal-massaging madness.
The Heart of a Predator
Pop the carbon-fiber hood (carefully, please) and you’re greeted by Wegner Motorsports’ 5.0-liter Whipple-supercharged Coyote V8 — the sort of engine that could frighten small gods and most traction control systems. Over 800 horsepower gallops through a Bowler Transmissions Carbon Edition six-speed manual, sending every last ounce of fury to the rear wheels.
It’s got a custom stainless-steel exhaust manifold and a Flowmaster Super 44 setup that sounds less like a car and more like a baritone apocalypse. It doesn’t purr — it snarls, coughs, and announces itself as KINGPIN, ruler of the asphalt underworld.
Bodywork by Blacksmiths with OCD
Ringbrothers didn’t just restore a Mustang. They re-engineered it. The body’s been widened by two inches up front and 3.5 inches out back, giving it a stance that looks ready to punch other cars out of its parking space. The front wheelbase stretches 1.5 inches, lending KINGPIN a crouched, aggressive posture — part predator, part muscle-car deity.
And while there’s still plenty of Detroit muscle in its bones, the outer shell is draped in carbon fiber — the hood, grille surround, front lip, rear diffuser, and side panels all painstakingly woven to perfection. The color? A deep, sultry Bootleg Blag that catches light like polished obsidian.
Under the Skin
Beneath the sheetmetal, there’s proper engineering wizardry: independent front and rear suspension, Fox RS adjustable dampers, and enough Brembo stopping power to halt the Earth’s rotation. The HRE Vintage 517 wheels, wrapped in Michelin Pilot Sport 4S tires, complete the look — a nod to vintage racing wrapped in modern grip.
Interior: Subtle Mayhem
Inside, KINGPIN blends race-ready focus with designer swagger. There’s a chopped carbon steering wheel, Dakota Digital gauges, and a bespoke roll cage tucked neatly into the cabin. Even the climate controls look like they were designed by someone who builds stealth fighters on the weekend.
And the paint? Oh, it’s Grab-Her Green — Ringbrothers’ cheeky reinterpretation of Ford’s classic Grabber Green. It’s just a shade off, deliberately so. A little smirk in color form.
KINGPIN isn’t a restomod. It’s a statement. It’s proof that the American muscle car can evolve without losing its snarl — that craftsmanship still matters in an age of touchscreen horsepower.
Ringbrothers haven’t just built a Mustang. They’ve built an event.
If this thing doesn’t make you want to burn rubber and confess your automotive sins, check your pulse — you might already be dead.
