Ringbrothers KINGPIN Mach 1 Is The Ultimate 800-HP Classic Rebuild

Ringbrothers dropped something nasty at SEMA this year. They call it KINGPIN. It started life as a 1969 Mustang Mach 1, and after 5,500 hours of cutting, welding, and pure stubbornness, it came out the other side as a proper show-and-go menace.

Jim Ring put it bluntly: What would the final boss in a John Wick film drive? KINGPIN is that answer. The body’s wider, the wheelbase is stretched, and the whole shell has been reworked into a single-piece unibody, so it sits like it means business. Looks low, feels mean. Simple as that.

Under the dark BASF Bootleg Black and acres of carbon sits a Wegner Motorsports 5.0-liter Coyote V8, fed by a Whipple supercharger and tuned well north of 800 horsepower. Power goes to the back through a Bowler Carbon Edition six-speed manual. The headers are custom, the cans are Flowmaster Super 44s, and the soundtrack? Properly rude.

Chassis and grip are sorted, too. FAST TRACK Stage III bones, Fox coilovers, Michelin Pilot Sport 4S rubber, and big Brembo stoppers. This thing isn’t just for looking mean under lights—it’s built to hustle, corner hard, and stop on a dime.

Design-wise, Ringbrothers walked a line. It’s still unmistakably a Mach 1, but every line’s been sharpened. There’s a cheeky nod to Ford in the Grab-Her Green trim, but most of the surfaces are shaved carbon and purpose. The silhouette reads classic; the details read weaponized.

Inside is the same mix of retro and modern. Crushed-carbon wheel, Dakota Digital gauges, machined metal trim, and vintage-style HVAC bits. It feels put together, not pasted on. Like someone rebuilt the past with today’s toolkit.
